Conflicting reports emerged Saturday about President Trump's health and the timeline of when he was first tested positive for the coronavirus.
Trump is "doing very well," his physician told reporters on Saturday morning, but a source familiar with the president's health later told White House pool reporters, that "the president's vitals over the last 24 hours were very concerning." The Associated Press identified that information as coming from White House Chief of Staff Mark Meadows.
