Lingering anger from Joe Biden's staffers at him dropping out of the race after a relentless campaign from Democrats to oust him has led to tension with Kamala Harris' campaign team, a bombshell report reveals.

Biden, 81, has appeared to undercut Harris at least four times in recent weeks during the critical final stages of the 2024 race that could be one of the closest in history.

He made a surprise White House briefing room appearance during one of her rallies and praised Ron DeSantis' response to the hurricanes that devastated his state, while she accused him of playing politics. 

Now a new report from Axios with quotes from 10 anonymous insiders says  resentment from bruised Biden aides has led to friction.
