• Senator Bernie Sanders stands by Clinton saying she will "make an outstanding president".
• First Lady Michelle Obama addresses the delegates saying "when they go low, we go high".
• Debbie Wasserman Schultz booed
Day one of the Democratic National Convention has wrapped up.
As it happened:
3.23pm: "I have known Hillary Clinton for 25 years. I remember her as a great first lady who broke precedent in terms of the role that a first lady was supposed to play as she helped lead the fight for universal health care. I served with her in the United States Senate and know her as a fierce advocate for the rights of children.
"Hillary Clinton will make an outstanding president and I am proud to stand with her here tonight."
3.19pm: Sanders says: "In these stressful times for our country, this election must be about bringing our people together, not dividing us up. While Donald Trump is busy insulting one group after another, Hillary Clinton understands that our diversity is one of our greatest strengths. Yes. We become stronger when black and white, Latino, Asian-American, Native American - all of us - stand together. Yes. We become stronger when men and women, young and old, gay and straight, native born and immigrant fight to create the kind of country we all know we can become.
"It is no secret that Hillary Clinton and I disagree on a number of issues. That's what this campaign has been about. That's what democracy is about. But I am happy to tell you that at the Democratic Platform Committee there was a significant coming together between the two campaigns and we produced, by far, the most progressive platform in the history of the Democratic Party."
3.15pm: "This election is about climate change, the greatest environmental crisis facing our planet, and the need to leave this world in a way that is healthy and habitable for our kids and future generations. Hillary Clinton is listening to the scientists who tell us that - unless we act boldly and transform our energy system in the very near future - there will be more drought, more floods, more acidification of the oceans, more rising sea levels. She understands that when we do that we can create hundreds of thousands of good-paying jobs.
"Donald Trump? Well, like most Republicans, he chooses to reject science. He believes that climate change is a "hoax," no need to address it. Hillary Clinton understands that a president's job is to worry about future generations, not the short-term profits of the fossil fuel industry."
3.14pm: "This election is about the thousands of young people I have met who have left college deeply in debt, and the many others who cannot afford to go to college. During the primary campaign, Secretary Clinton and I both focused on this issue but with different approaches. Recently, however, we have come together on a proposal that will revolutionise higher education in America. It will guarantee that the children of any family this country with an annual income of $125,000 a year or less - 83 percent of our population - will be able to go to a public college or university tuition free. That proposal also substantially reduces student debt."
3.08pm: "Hillary Clinton understands that if someone in America works 40 hours a week, that person should not be living in poverty. She understands that we must raise the minimum wage to a living wage. And she is determined to create millions of new jobs by rebuilding our crumbling infrastructure - our roads, bridges, water systems and wastewater plants.
"But her opponent - Donald Trump - well, he has a very different view. He does not support raising the federal minimum wage of $7.25 an hour - a starvation wage. While Donald Trump believes in huge tax breaks for billionaires, he believes that states should actually have the right to lower the minimum wage below $7.25. What an outrage!"
2.58pm: "I understand that many people here in this convention hall and around the country are disappointed about the final results of the nominating process. I think it's fair to say that no one is more disappointed than I am. But to all of our supporters - here and around the country - I hope you take enormous pride in the historical accomplishments we have achieved."
"This election is not about, and has never been about, Hillary Clinton, or Donald Trump, or Bernie Sanders or any of the other candidates who sought the presidency. This election is not about political gossip. It's not about polls. It's not about campaign strategy. It's not about fundraising. It's not about all the things the media spends so much time discussing.
"This election is about - and must be about - the needs of the American people and the kind of future we create for our children and grandchildren."
2.51pm: Sanders has thanked Michelle Obama for her "incredible service to our country".
"She has made Americans proud."
2.50pm: Bernie Sanders has been introduced.
2.45pm: Warren says Trump's entire campaign is just one more long Trump infomercial.
"Hand over your money... and the great Trump hot air machine will hand over all the answers. And for one low-low price, he'll even throw in a goofy hat!"
Warren says the choice in the presidential election is clear, and she says Republican nominee Donald Trump "cares about himself every minute of every day."
Warren tells the crowd: "I'm with Hillary. This choice is personal. It's about who we are as a people."
Warren says "there's lots of wealth in America" but "it isn't trickling down to families like yours."
Instead, she tells delegates, the "system is rigged" as "Americans bust their tails" while "wages stay flat."
Warren rejects those who say such an economy is a result of a Congress that isn't working. She says Congress works fine when corporations and the wealthy seek tax breaks and favorable regulations.
But she says, "try to do something for working people," and the "gridlock" ensues.
Warren says GOP presidential nominee Donald Trump's "whole life has been about taking advantage of that rigged system."
2.40pm:"Trump thinks he can win votes by fanning the flames of fear and hatred. By turning neighbor against neighbor. By persuading you that the real problem in America is your fellow Americans - people who don't look like you, or don't talk like you, or don't worship like you."
2.37pm: The Honorable Elizabeth Warren, United States Senator, Massachusett has criticised Trump
"Not once did he lift a finger to help working people... time after time, he preyed on working people, people in debt... he's conned them, he's defrauded them and he's ripped them off"
"I wake up every morning in a house that was built by slaves. And I watch my daughters, beautiful intelligent black young women, playing with their dog on the White House lawn.
"And because of Hillary Clinton, my daughters and all our sons and daughters, now take for granted that a woman can be president of the United States.
"So don't let anyone ever tell you that this country isn't great. That somehow we need to make it great again. Because this right now is the greatest country on earth.
"We need to do what we did four years ago and eight years ago" and elect Hillary Clinton president."
Michell Obama says Clinton "has the guts and the grace to keep coming back and putting cracks in that highest and hardest glass ceiling until she finally breaks through, and lifts all of us with her."
2.16pm: Michelle Obama has praised Hillary Clinton's reaction after losing back in 2008.
"What I admire most about Hillary is that she never [folds] under pressure. She never takes the easy way out.
"That's what I want. I want someone who has the proven strength to persevere."
2.13pm: Michelle Obama says this election is not about Democratic or Republican but rather is about "who will have the power to shape our children for the next four or eight years of their lives."
"In this election there is only one person who I trust with that responsibility.. and that is our friend Hillary Clinton."
2.08pm: "It's hard to believe that it has been eight years since I first came to this convention," Michelle Obama says.
The first lady talks about her daughters and "the joy of watching them grow."
"I will never forget that winter morning as I watched our girls, just 7 and 10 years old, pile into those black SUVs with so many men with guns, their little faces pressed to the windows, and I thought, what have we done?"
She says "we urge them to ignore those who question their father's citizenship or faith.. we insist" that hateful language does not represent the country.
"How we explain that when someone is cruel and acts like a bully, you don't stoop to their level. No, our motto is, when they go low, we go high."
Cheryl Lankford, whose husband, an army sergeant major, died in Baghdad in 2007 is speaking now.
The Democrats air a video of Lankford telling the story of being taken for $35,000 by Trump University.
"I'm here because America deserves to know the truth. This election isn't about Democrat versus Republican. It's about right versus wrong."
Donald Trump made big promises about Trump University. And I was fooled into believing him. Now he's making big promises about America. Please don't make the same mistake."
2pm: Michelle Obama is due to speak next.
1.45pm: The Honorable Cory Booker, United States Senator, New Jersey is speaking.
"We have a presidential nominee in Hillary Clinton who knows that, in a time of stunningly wide disparities of wealth in our nation, America's greatness must not be measured by how many millionaires and billionaires we have, but by how few people we have living in poverty."
"Hillary knows when workers make a fair wage, it doesn't just help their families, it builds a stronger, more durable economy that expands opportunity and makes all Americans wealthier."
"She knows that in a global knowledge-based economy, the country that out-educates the world will out-earn the world, out-innovate the world, and lead the world."
"She knows that debt-free college is not a gift, it's not a charity, it's an investment. It represents the best of our values, the best of our history, the best of our party: Bernie's ideas, Hillary's ideas, our shared ideas. Our shared values.
"Hillary Clinton knows what Donald Trump betrays time and again in this campaign: that we are not a zero sum nation, it is not you or me, it is not one American against another. It is you and I together, interdependent, interconnected with one single interwoven American destiny."
1.35pm: Actress and activist Eva Longoria has said she's proud to say "I'm with her!"
"When Donald Trump calls us criminals and rapists, he's insulting American families. My father was not a criminal or a rapist. In fact he's a United States veteran.
"Hillary's been fighting for us for decades. Now it's time to fight for her!"
Paul Simon is now performing.
1.15pm: Sarah Silverman and Senator Al Frankin are now on the stage.
Sarah Silverman has addressed her support for Bernie Sanders.
"Not only did Bernie wake us up he made us realise what is possible and what we deserve," she said.
Hillary heard the passion of the people, the people behind Bernie and brought those people on board she said.
"That is democracy at its best.
"It's so inspiring. Just a few months ago she was a secretary and now she could be president!
"She's like the only person to be overqualified for the job as the president. So I tell you this, I will vote for Hillary with gusto.
"I am proud to be part of Bernie's movement. And a big part of that movement is to make absolutely sure that Hillary Clinton is elected president of the United States."
She said to the "Bernie or bust" people: "You're being ridiculous".
"Thank God they can fix this in post [production]," she jokes.
1.05pm: Anastasia Somoza, who, along with her twin sister, was diagnosed with cerebral palsy and spastic quadriplegia when she was born and is an advocate for Americans with intellectual and developmental disabilities and supports Hillary Clinton.
Somoza first met President Bill Clinton in 1993 at a town hall meeting for kids and is a former Hillary Clinton intern.
"Donald Trump has shown us who he really is," she said.
"I honestly feel bad for anyone with that much hate in their heart. I know we will show each other, and the world, who we really are in November - when we choose genuine strength and thoughtful leadership - over fear and division. Donald Trump doesn't see me, he doesn't hear me, and he definitely doesn't speak for me."
She said she is confident confident Hillary Clinton will do everything in her power to support the rights and humanity of all Americans.
12.56pm: US Senator Al Franken has the crowd laughing with his digs at Donald Trump.
I'm Al Franken. Minnesota Senator and world renowned expert on right wing megalomaniacs: Rush Limbaugh, Bill O'Reilly, and now, Donald Trump," he said introducing himself.
"I got my doctorate in megalomania studies from Trump University," Franken said.
"As a proud alum of Trump U, I think we may be misunderestimating Mr Trump. Sure he's scammed a lot of people, but did you know that Mr Trump's school of ripping people off is ranked second in the nation? Right behind Bernie Madoff University."
"I think rather than voting for someone who's never done anything other than himself, maybe we should vote for a candidate" who's devoted her life to improving the lives of other people, Franken said.
"I am proud to call Hillary Clinton my friend and I can't wait to call her madam President."
The Honorable Kirsten Gillibrand, United States Senator, New York, is now speaking.
"Like most working parents my husband and I juggle a lot ...some days we barely keep it together.
"The vast majority of working parents have it a lot tougher ...Washington hasn't caught up to their reality," she said.
She said policies are stuck "in the Mad Men era".
"We know when families are strong America is strong, Hillary Clinton gets it ...it's about her core values, the idea we have that we have a responsibility to one another."
"It's why as President she will bring our workplace policies out of the dark ages and always, always put families first."
12.41pm: A police spokesman says there are no immediate injuries being reported from the strong storm that led protesters to seek shelter under highway underpasses during the convention.

"I don't deel brave every day, most days I'm scared my mum and my dad will be forced to leave and I wonder what if I come home and find it empty," she said.
"I was to grow up to be a lawyer so I can help other families like us.
"Hilary Clinton told me that she would do everything she could to help us ...that she will be the worrying for me."
Singer-songwriter Demi Lovato is speaking about mental illness.
"Like millions of Americans, I am living with mental illness. But I am lucky. I had the resources and support to get treatment at a top facility. Unfortunately, too many Americans from all walks of life don't get help, either because they fear the stigma or cannot afford treatment.
"Untreated mental illness can lead to devastating consequences, including suicide, substance abuse, and long-term medical issues. We can do better. Every one of us can make a difference. By getting educated on this epidemic and its frightening statistics and by breaking the stigma, I urge every politician to support laws that will provide access to better healthcare and support for everyone.
"This is not about politics. It's simply the right thing to do. I'm doing my very small part by having the treatment center that saw me through my recovery on tour with me so that at least a small group of people, even for a brief moment, have the same support that I received.
"It may not be a lot but we have to believe every small action counts. I stand here today as proof that you can live a normal and empowered life with mental illness."

Outgoing Democratic National Committee Chair Debbie Wasserman Schultz will excuse herself from gavelling in the party's national convention Tuesday, bowing to heavy opposition from party activists following the leak of a trove of embarrassing DNC emails.
"I have decided that in the interest of making sure that we can start the Democratic convention on a high note that I am not going to gavel in the convention," Wasserman Schultz told the Sun Sentinel newspaper in Florida, which first reported her plans.
The decision was one of many dramatic developments during a day of discord that threatened to distract from a lineup of high-profile speeches meant to convey Democratic unity on the first day of the convention. The FBI said it was investigating the email breach that triggered much of the inta-party friction over the weekend.
The leak of emails that showed DNC staff apparently scheming to help Clinton win the Democratic primary looms over the four-day convention. Wasserman Schultz resigned her post effective at the end of the event.
Vermont Senator Bernie Sanders, Clinton's main primary challenger, was cheered by supporters at a rally Tuesday when he smiled and told the crowd that the Florida congresswoman's departure would "open the door" for new leaders to take the reins.
"Her resignation opens up the possibility of new leadership at the top of the Democratic Party that will stand with working people," Sanders said.
Minutes later, when Sanders encouraged Democrats to elect Clinton and her running mate, Virginia Senator Tim Kaine, the crowd started booing loudly.
Sanders tried to talk them back, arguing that Republican nominee Donald Trump "must be defeated."
Wasserman Schultz faced an angry backlash at a meeting of her home state activists hours earlier. And liberal delegates stood ready to shower her with boos if she had stepped onto the stage at the convention, according to a top Democrat familiar with their plans.
The FBI released a statement Tuesday saying that the agency was "investigating a cyber intrusion involving the DNC and are working to determine the nature and scope of the matter. A compromise of this nature is something we take very seriously, and the FBI will continue to investigate and hold accountable those who pose a threat in cyberspace."
As she took the podium at a Florida delegation breakfast, the South Florida congresswoman faced boos, which competed with many of the cheers she received.
"If I could ask everybody to settle down," she told the rowdy crowd as she struggled to maintain order. Moments later she repeated herself: "All right everybody, now settle down. Settle down, please."
Another official then stepped in to try to restore order.
Trying to speak over the noise, Wasserman Schultz acknowledged, "There's a little bit of interest in my being here, and I appreciate that interest."
Wasserman Schultz is preparing to leave Philadelphia and return to Florida, according to two people familiar with ongoing discussions who asked for anonymity to describe private conversations. Spokespeople for the Clinton campaign and DNC didn't return requests for comment.
Convention officials are hoping to move past the drama as the evening approaches. Two of the Democratic Party's most popular liberal stars - Sanders and Massachusetts Sen. Elizabeth Warren, the keynote speaker - will give speeches Monday night. First lady Michelle Obama will also address the convention.
Addressing supporters Tuesday, Sanders reflected on what he sees as key accomplishments during and after his campaign. He praised supporters for helping secure "by far the most progressive platform ever written in the history of the Democratic Party" here at the convention.
"We showed in a way that will change politics in our country forever that you can run a competitive national campaign without begging billionaires for campaign contributions," said Sanders.
Volunteers from the Sanders campaign were trying to pressure convention organisers for roll call votes on the presidential and vice presidential nominations, which would stretch out the process and highlight pockets of disagreement.
The Clinton campaign said there will be a roll-call vote on the nomination of Clinton to be president.
"We anticipate there will be a roll-call vote tomorrow night and that every vote will be counted, that we'll go through all 50 states. We're happy to have it," said Clinton campaign spokesman Brian Fallon. Fallon said he wasn't sure whether the plan extended to the vice presidential process.
Sanders's address will be closely watched following months of bruising competition with Clinton that left many of his supporters deflated and angry with the process. Those hard feelings threatened to boil over again here Tuesday after the email leak showed party strategists appearing to plot against him during the campaign.
In an interview on MSNBC Tuesday Clinton campaign chairman John Podesta said the campaign had not seen a copy of the Vermont senator's speech.
Wasserman Schultz was pushed to resign by the release of thousands of emails among party officials that appeared to show coordinated efforts to help Clinton at the expense of her rivals in the Democratic primaries. That undercut claims by the party and the Clinton campaign that the process was open and fair for Sanders.
"It's best for Hillary Clinton that we have a new chair of the party. We'll have that with Donna Brazile," Podesta said on MSNBC. Brazile, a veteran party strategist, will take over as interim chair.
The email messages released by hackers were posted Saturday on the website WikiLeaks.
The Clinton campaign - and several cybersecurity experts - said the leak was a political ploy carried out by the Russian government to aid in the election of Trump. National security officials are increasingly concerned about possible efforts by Russia to meddle in the election, according to several individuals familiar with the situation.
Mook said that the DNC has begun a comprehensive review of its internal emails to determine what damaging correspondence might be in the hands of Russian hackers.
Wasserman Schultz has been told to be prepared for an unwelcome reception, had she opened the convention, the Democrat familiar with the plans to protest her said.
Republicans, led by Trump, jumped to portray the leaked email episode as evidence that the system was rigged for Clinton, whom Trump calls "Crooked Hillary."
"The State of Florida is so embarrassed by the antics of Crooked Hillary Clinton and Debbie Wasserman Schultz that they will vote for CHANGE!" Trump tweeted Tuesday.
As Democrats start their convention, Trump will be campaigning in two swing states: Virginia and North Carolina.
Also campaigning in North Carolina Tuesday, Clinton took a swipe at Trump, who once said he counted heavily on himself for foreign policy advice.
"You will never hear me say that I only listen to myself on national security," Clinton said.
A pair of new polls released Tuesday showed a competitive race heading into the convention. A CNN/ORC survey conducted after the GOP convention showed Trump jumping ahead of Clinton. A CBS News poll showed that the contest is effectively tied.
Even Clinton's party was doing battle with itself, she picked new Democratic support, as former vice president Al Gore endorsed her on Twitter.
Throughout the first day of the convention, Democrats are expected to try to cast a spotlight on Clinton's work on behalf of families.
Later in the week, the party stalwarts will hear from President Obama, Vice President Biden and former president Bill Clinton, among others. The convention will culminate Thursday in a speech from Hillary Clinton, who is poised to make history as the first woman to be nominated for president by a major party.
Democrats were hoping to showcase a smooth, error-free convention that would contrast sharply with last week's Republican gathering in Cleveland, which was marred by plagiarism and intra-party skirmishes.
Instead, the email leaks and the upheaval at the top ranks of the party threatened to upend Clinton's plan to paint the Democrats as the party best prepared to lead a divided and anxious country and herself as the leader who can offer an optimistic alternative to Republican nominee Donald Trump.
While Brazile is taking over as interim chair, discussions were underway Monday about who might be suitable to step in as chair between now and the November election. Among the Democrats mentioned: former Michigan governor Jennifer Granholm, Rep. Steve Israel of New York and EMILY's List President Stephanie Schriock. All are loyal supporters and trusted allies of Clinton.
The emails revealed a DNC official apparently discussing how to use Sanders's religion against him to help Clinton ahead of the Kentucky and West Virginia primaries. In another email, a Clinton campaign lawyer suggested to the DNC how it should respond to claims from the Sanders campaign that it was improperly using a joint fundraising committee with state parties.
The Washington Post reported last month that Russian government hackers penetrated the DNC, stealing opposition research about Trump and compromising the party's email and chat systems.
In addition to the friction with Sanders and his supporters that was revealed in the email hack, donors were upset about the way they were talked about in some of the emails.
Clinton issued a statement Sunday in which she announced that Wasserman Schultz would serve as honorary chair of the campaign's 50-state program as well as continuing as a surrogate nationally and in Florida.
