In a 1999 interview from Maher's of "Politically Incorrect," the Delaware Republican Senate candidate said that before she became a Christian she tried several religions, but skipped becoming a Hare Krishna because she didn't want to be vegetarian.
Maher aired the clip of O'Donnell Friday night on his show "Real Time with Bill Maher."
A video of the clip was later posted on the Think Progress website:
O'Donnell: "I was dabbling into every other kind of religion before I became a Christian."
Maher: "You were a witch!"
O'Donnell: "I was! I was!"
Maher: "You were."
O'Donnell: "I was dabbling in witchcraft. I've dabbled in Buddhism. I wanted to become a Hare Krishna but I didn't want to become a vegetarian. And that is honestly the reason why - because I'm Italian, I love meatballs."
Maher: "Boy, are you spiritual."
It's the third clip of O'Donnell that Maher has shown since she won her state's GOP primary last month.
The interview, originally broadcast on ABC on July 9, 1999, actually predates the interview clip released by Maher two weeks ago in which O'Donnell admitted to having "dabbled into witchcraft."
Reached by phone, O'Donnell campaign spokesman Chris Merola had no immediate comment.
