Former Democratic presidential candidate calls out 'mistake' in Biden's letter to fellow Democrats

A familiar face of America’s past political landscape has criticized Joe Biden’s letter to his party and finds it more "harmful" than helpful for the 46th president.

"I read that letter," former Nebraska senator, governor and 1992 Democratic presidential candidate Bob Kerrey said on "The Claman Countdown" Monday.

"If I was a Democratic member of Congress, I'd call the White House and say, ‘You made a mistake. You don't send this letter out to us,’" he continued. "If I question [whether] you can defeat Donald Trump, I'm bad for democracy? It's blatantly untrue, it's self-serving and not helpful."

On Monday morning, President Biden urged his colleagues to stop questioning whether he should end his re-election bid and "move forward as a unified party" in order to defeat former President Donald Trump in their 2024 election rematch.

Biden also reiterated that he's "firmly committed to staying in this race" and argued that any further questioning of his candidacy "only helps Trump and hurts us."

The president’s fitness for office has come into question following his rough debate performance a week and a half ago in his first face-to-face showdown with Trump.
