US President Donald Trump was ushered from a press conference by the Secret Service after authorities shot a person outside the White House.
A member of Trump's team told him to leave the podium during the press briefing.
Trump was interrupted while speaking to reporters about Covid-19 , asking the staff member "excuse me?" before hurriedly leaving the room.
The President later returned to the briefing, and said a "shooting" outside the White House was now "under control".
"There was an actual shooting and somebody's been taken to the hospital," Trump said.
The President said the shots were fired by law enforcement, saying he believed the individual who was shot was armed.
"It was the suspect who was shot," Trump said.
The suspect was taken to a local hospital, and the District of Columbia fire department said the man suffered serious or possibly critical injuries
Law enforcement officials were still trying to determine the suspect's motive.
Authorities were investigating whether the individual has a history of mental illness.
Trump said he was escorted to the Oval Office by the agent. The White House was placed on lockdown.
Trump praised the work of Secret Service personnel for their work in keeping him safe.
Trump: 'Do I seem rattled?'
Reporters peppered Trump with questions when he returned to the briefing room.
Asked if he was taken to the bunker under the White House, Trump replied, "no, we were taken just out to the Oval Office".
The President was also asked if he was rattled, he said, "I don't know, do I seem rattled?"
"I feel very safe with the Secret Service, they're fantastic people, they're the best of the best, they're highly trained," Trump told reporters.
"They just wanted me to step aside for a little while just to make sure that everything was clear outside."
The shooting happened near 17th St and Pennsylvania Ave just blocks from the White House, according to two sources with knowledge of the situation but who were not authorised to speak publicly about it.
Law enforcement officials were still trying to determine the suspect's motive.
Trump says he's 'very safe'
"Was the suspect armed?" one of the reporters asked on his return.
"From what I understand, the answer is yes," Trump replied. "That's what I understand. I don't know. You'll have to ask them."
Asked whether the suspect had said anything about him, Trump said he didn't know.
"It might not have had anything to do with me. It might have been something else," he said.
"But it was on the outside of the premises. The wall - as you know, the fencing, especially the new fencing that they put up, is very powerful. But it was on the outside of the White House.
"It's unfortunate that this is a world - but the world's always been a dangerous place. It's not something that's unique. The world has been - you look back over the centuries, the world has been a dangerous place.
"It will continue, I guess, for a period of time."
Trump stressed that he feels "very safe with the Secret Service".
