BETHESDA, Md. (AP) — President Donald Trump hoped for a Monday discharge from the military hospital where he is being treated for COVID-19, a day after he briefly ventured out  to salute cheering supporters by motorcade.

The scale of the outbreak within the White House itself was still being uncovered Monday, as press secretary Kayleigh McEnany announced she tested positive for the virus Monday morning and was entering quarantine.

White House officials said Trump was anxious to be released after three nights at Walter Reed National Military Medical Center, where doctors revealed on Sunday that his blood oxygen level had dropped suddenly twice in recent days and that they gave him a steroid typically only recommended for the very sick. Still, the doctors said Trump’s health was improving and he could be discharged as early as Monday to continue the remainder of his treatment at the White House.

Trump “is ready to get back to a normal work schedule” and was optimistic about a Monday release, White House chief of staff Mark Meadows told Fox News. He said a determination would be made after further evaluation by his medical team later Monday.
