Biden turns 80, becomes first-ever President to serve at that age

It's been a busy weekend for U.S. President Joe Biden — but not because of work.

Yesterday, Biden's granddaughter got married at the White House.

And today, his family got together again to celebrate his birthday. Biden is now the first sitting U.S. president to turn 80.

As Mike Armstrong reports, critics wonder if the oldest commander-in-chief might be too old.
