In a video posted on social media, the oldest president in US history appears to be trying to regain his balance as he boards the presidential plane, Air Force One.
We see him walking up the stairs, and when he reaches the floor he turns around and appears to be looking for a place to stand.
This is not the first time that Biden has faced doubts about his health. Over the past year, he has been seen stumbling down the stairs and making confusing statements during speeches.
However, the Democratic candidate for the presidential elections in November successfully passed his annual medical examination last February.
