Age questions continue to dog 78-year-old Biden

President Biden moves more slowly than when he was vice president under former President Barack Obama. He squints slightly when looking at the teleprompter and sometimes misspeaks anyway.

Before taking office, Biden suffered a minor injury in a fall (the transition office said at the time that he tripped while playing with his dog). Since then, he has yet to hold a solo press conference. Reporters are sometimes shooed away at his public events, where his wife, Vice President Kamala Harris, or aides can be seen pointing him in the right direction.
