US President Donald Trump has completed his course of treatment for Covid-19 and can return to public engagements this weekend, his physician has said.
Dr Sean Conley said the president had responded "extremely well" to medication and had "remained stable".
Mr Trump later said he would probably take another Covid test on Friday and hoped to hold a rally over the weekend.
The president earlier pulled out of next Thursday's TV debate with Democratic rival Joe Biden.
He said he was "not going to waste my time on a virtual debate" after organisers said it would have to take place remotely because Mr Trump had tested positive for coronavirus.
The move sparked a row about how and when further debates would take place.
Meanwhile, House Speaker Nancy Pelosi, the most powerful Democrat in Washington, said serious questions concerning Mr Trump's health were still unanswered.
She said she planned to introduce legislation on Friday to establish a commission to assess the president's fitness for office and "help ensure effective and uninterrupted leadership".
A statement announcing the move said the commission would be set up under the 25th Amendment, which outlines how a sitting president can be stripped of power if they are deemed unable to conduct the duties of the office.
Mr Trump responded to the announcement on Twitter, calling Ms Pelosi "crazy".
What's the latest on Trump's health?
In a memo released by the White House on Thursday evening, Dr Conley said Mr Trump was displaying no signs "to suggest progression of illness".
"Saturday will be day 10 since [last] Thursday's diagnosis, and based on the trajectory of advanced diagnostics the team has been conducting, I fully anticipate the president's safe return to public engagements at that time," the memo added.
Earlier, Dr Conley said that if the president's condition remained the same or improved throughout the weekend and into Monday, "we will all take that final, deep sigh of relief".
Speaking to Fox News late on Thursday, Mr Trump said he was feeling "really good" and hoped to hold a campaign rally on Saturday evening, possibly in Florida.
