U.S. President Joe Biden is doing fine after stumbling on the steps as he climbed aboard AirForceOne on Friday, White House spokeswoman Karine Jean-Pierre told reporters.
She suggested high winds at Joint Base Andrews near Washington may have been a factor.
Boarding a flight to Atlanta, where he was to speak to the Asian-American community about a shooting there this week, Biden stumbled slightly about halfway up the 25 or so stairs, recovered, then stumbled again and briefly went down on one knee, according to video footage.
The president appeared to rub his left knee before getting back up, then completed the stairs at a slower pace. He stopped at the top of the stairs, turned around and offered a crisp salute.
