Viral video has shown the moment President Joe Biden stumbled three times and fell on the steps of Air Force One on Friday.
The 78-year-old – the oldest president in US history – appeared to struggle as he boarded the presidential plane, prompting fresh questions about his health.
It was not immediately clear what tripped Biden up the first time, but shortly after recovering he fell twice more before dusting himself off. Security officials, meanwhile, looked on with concern from the ground.
The president recovered to give a salute at the top of the stairs before departing to meet with Asian American community leaders in the wake of the massage parlour massacre in Atlanta, Georgia.
