President Joe Biden is the oldest sitting president in US history. He's 81 years old and turns 82 in November, just a few weeks after the election.

And his age has come up a lot during his re-election campaign.

President Biden's age is an enormous issue.

That's our colleague Chivon Hughes, who covers Congress.

It shows up in polls as being a top issue.

You can't really overstate the degree to which age

overhangs the entire 2024 election. When I interview voters and say that I

cover the White House, the first question I get across the board is what is he actually like and is his age affecting him.

And that's our colleague Annie Linsky, who covers the White House.

Together, Chivon and Annie have been looking into what impact, if any,

Biden's age is having on his ability to do his job as president.

I mean, it's something that people are just constantly evaluating.

White House officials and other Democrats

acknowledge that Biden is getting older.

But they say that behind closed doors,

he's as strong and as dynamic as ever.

They would say if only if only the American people could see the Joe Biden that we see every day.

He is sharp as a tag. He is on top of it. He is sharp, intensely probing and

detail-oriented and focused. He's asking detailed questions about policy.

He's smart, he's on his game.

He is a different person than the one that you see publicly.

But, you know, we see the president publicly and he has been making slips and we see him on stage, we see him at speeches, but what is he like behind closed doors?
