Mark Meadows: Trump's blood oxygen level "dropped rapidly," but he's doing well

White House Chief of Staff Mark Meadows told Fox News Saturday night that officials were "concerned" about President Trump's condition after he was diagnosed with the coronavirus, but he's now "doing well."

Why it matters: There have been conflicting reports from the White House on Trump's condition. Meadows' remarks come after White House physician Sean Conley said Saturday that Trump "remains fever-free and off supplemental oxygen," but that the president is "not yet out of the woods."

• Trump said in a video message released earlier Saturday that he's "starting to feel good." The White House later released images of him at work in the Walter Reed Medical Center.

What he's saying: "The biggest thing that we see is ... with no fever now and with him doing really well with his oxygen saturation levels, we — yesterday morning, we were real concerned with that," Meadows told Fox News' Jeanine Pirro.

• "He had a fever and his blood oxygen level had dropped rapidly ... and yet, in typical style, this — this president was ... walking around and, even as the experts from the medical facilities not only at Walter Reed but also Johns Hopkins, got there, they — they looked at his situation and recommended that, out of an abundance of caution, that he come here to Walter Reed," Meadows added.
