Biden makes first appearance since dropping out of the race
Biden briefly spoke with reporters as he boarded Air Force One at Dover Air Base on Tuesday.
The president, who tested negative for COVID-19, said he was "feeling well," and didn't respond to questions about bowing out of the race.
Biden had a mask in hand, which he placed in his pocket after he got out of the car before getting on the plane.
The president gave a salute and a thumbs up as he boarded.
