President Joe Biden stumbled while climbing a short flight of stairs at an event in Philadelphia. Despite the stumble, he quickly regained his balance and delivered a speech on 'Bidenomics' and investing in the U.S. This is not the first time Biden has stumbled, as he has had previous incidents while de-boarding Air Force One and at a Coast Guard Academy graduation. The president, who is 80 years old, is facing concerns about his age and performance.
