'You lost all credibility': Dem insider punches hole in Tapper's Biden book

During an appearance on MSNBC on Sunday morning, former Democratic National Committee Chair and Jamie Harrison disputed comments attributed to him in CNN host Jake Tapper and Axios reporter Alex Thompson's controversial book about former President Joe Biden.

After discussing the internal warfare currently in play within the DNC, "The Weekend" co-host Eugene Daniels asked Harrison about the book "Original Sin," and noted that Thompson appeared on the show on Saturday.

That was when the ex-DNC chair went off.
