President Donald Trump was flown to Walter Reed Medical Center Friday night, after testing positive for coronavirus on Thursday.

Saturday morning, Dr. Sean Conley, Physician to the president, says Trump has been fever free for 24 hours, and is not on oxygen.

“At this time the team and I are extremely happy with the progress the President has made,” said Dr. Conley. “Thursday, he had a mild cough and some nasal congestion, and fatigue all of which are now resolving and improving.”

Dr. Conley did not say when Trump would be discharged, but that days 7 to 10 were the most critical in determining the course of the illness.

Dr. Conley said that Trump had been given Remdesivir, and an received an experimental treatment, Regeneron’s REGN-COV2, which is an experimental coronavirus drug.

“Given that we provided some of these advanced therapies so early in the course, a little bit earlier than most of the patients we know and follow, it’s hard to tell where he is on that course,” said Dr. Conley. “So, everyday we are evaluating, ‘Does he need to be here?’ ‘What does he need?’ and ‘Where is he going?'”

Dr. Sean Dooley, who’s part of the medical team overseeing the president, said that Trump seems to be in good spirits.

“The quote he left us with was, ‘I feel like I could walk out of here today,” and that was a very encouraging comment from the president.”

Conley said Trump has plenty of work to get done and he is doing it.

Former Indiana Governor, Vice President Mike Pence tested negative and has continued his campaign schedule. Indiana’s Amy Coney Barrett, US Supreme Court Judge nominee, also tested negative, but she did have a mild case of coronavirus earlier this year and recovered.
