text:  Good morning. So what do we know about how the president is doing? Last night, as he got on Air Force One to return from Las Vegas, the White House said he'd already taken his first dose of the antiviral drug Paxlovid and his symptoms were mild with a normal respiratory rate and temperature. But his cough was quite noticeable in an interview he did just before testing positive. We know that his doctor generally says he's in good health for his age.
