A look at where investigations related to President Donald Trump stand and what may lie ahead for him:

WHAT'S THIS ALL ABOUT?

Trump is facing investigations in Washington and New York.

Special counsel Robert Mueller is looking into whether the Trump campaign coordinated with Russia and whether the president obstructed the investigation. Trump also plays a central role in a separate case in New York, where prosecutors have implicated him in a crime. They say Trump directed his personal lawyer Michael Cohen to make illegal hush-money payments to two women as a way to quash potential sex scandals during the campaign.

WHAT DO I NEED TO KNOW?

Roger Stone, a longtime adviser and confidant of President Donald Trump, pleaded not guilty Tuesday to felony charges in the Russia investigation after a publicity-filled few days spent slamming the probe as politically motivated.

The political operative and self-described dirty trickster is accused of lying to lawmakers, engaging in witness tampering and obstructing a congressional investigation into possible coordination between Russia and Trump's 2016 presidential campaign.

Stone, 66, was uncharacteristically quiet during a brief court appearance, rising to his feet to say, "Yes, Your Honor," as U.S. Magistrate Judge Deborah Robinson asked if he would agree to the conditions of his release, including restricted travel. He remains free on $250,000 bond.

In Congress, lawmakers appear increasingly nervous that neither they nor the public will see a full report when Mueller completes his investigation. Republicans and Democrats both say they support public disclosure of Mueller's findings. But it's unclear exactly what document will be produced at the end of the probe.

SO ... DID THE TRUMP CAMPAIGN COLLUDE WITH RUSSIA?

There is no smoking gun when it comes to the question of Russia collusion. But the evidence so far shows that a broad range of Trump associates had Russia-related contacts during the 2016 presidential campaign and transition period, and several lied about the communication.

There is also evidence that some people in the president's orbit were discussing a possible email dump from WikiLeaks before it occurred. American intelligence agencies and Mueller have said Russia was the source of hacked material released by WikiLeaks during the campaign that was damaging to Hillary Clinton's presidential effort.

OTHER QUESTIONS TO CONSIDER:

—WHAT ABOUT OBSTRUCTION OF JUSTICE? That is another unresolved question that Mueller is pursuing. Investigators have examined key episodes such as Trump's firing of FBI Director James Comey and his fury over the recusal from the investigation by then-Attorney General Jeff Sessions.

—WHAT DOES TRUMP HAVE TO SAY ABOUT ALL THIS? Trump has repeatedly slammed the Mueller investigation as a "witch hunt" and insisted there was "NO COLLUSION" with Russia. He also says his former lawyer, Cohen, lied to get a lighter sentence in New York.
