Vice President Mike Pence will step up on the campaign trail as President Trump deals with a case of the coronavirus.

A campaign official told Fox News Saturday evening that Pence and the president had shared multiple phone calls since the president arrived at Walter Reed Medical Center Friday.

A campaign official said they expected additional events to be added to the vice president's schedule. Pence will be going to Utah for the vice presidential debate and then Arizona for events on Thursday.

The matchup between Pence and Sen. Kamala Harris, the Democratic nominee for vice president, will proceed as scheduled.

Meanwhile, President Trump remains at Walter Reed Medical Center, where he said he is "feeling well."

White House physician Dr. Sean Conley and other members of the medical team briefed reporters on Trump’s condition earlier in the day and said they were “extremely happy with the progress.”

President Trump was flown there Friday evening aboard the Marine One helicopter. He spent the night  and was “doing very well” as of Saturday afternoon, with no difficulty breathing. But an administration official warned that the next 48 hours would be “critical” to the president’s progress.

“Twenty-four hours ago, there was real concern about the President’s vitals," the official said. "For the past 12 hours, there has been zero concern.”
