Biden flip-flopped on anti-Buttigieg campaign ad, book claims

Then-candidate Joe Biden reluctantly approved a campaign ad bashing his then-primary rival Pete Buttigieg’s record as South Bend mayor only to demand it be taken down a few hours later, according to veteran author Bob Woodward's upcoming book.

Sarcastically, the ad says that both candidates has "taken on tough fights."

"Under the threat of nuclear Iran, Joe Biden helped negotiate the Iran deal," the ad said, before brightening the music up. "And under the threat of disappearing pets, Pete Buttigieg negotiated lighter licensing regulations on pet chip scanners."
