Knowing what the Constitutional status is for the vice president (should Pence stay in D.C., should he go to the White House, etc., to be available if needed) is hard to guess with all of the misdirection the public is getting from the various White House and Walter Reed spokes-people.

One source says Trump might return to the White House on Monday, other say he's still receiving the monoclonal antibody treatment for lung issues and his oxygen level dipped over the weekend.

Just before hitting "submit message" I looked at the New York Times, with this article:

"Trump’s oxygen levels dropped and he was given dexamethasone, potentially signaling a ‘severe’ case of Covid-19."

Steroids now.
