Christine O'Donnell walked out of an interview with CNN's Piers Morgan on the "Piers Morgan Tonight" show on Wednesday. The former Delaware U.S. Senate candidate took offense at the host's questions about gay marriage.

"I'm not being weird; you're being a little rude," O' Donnell said to the host, before storming off the program's set. 

O'Donnell appeared on the program to promote her nonfiction book, "Troublemaker", but got into a tiff with Morgan when he questioned her on her views on gay marriage and abstinence.

The interview began quite amicably with O'Donnell talking about her views on the Tea Party and the debt ceiling. Things turned sour when Morgan began questioning O'Donnell on her position on gay marriage. O'Donnell kept beating about the bush and evading his questions. This prompted Morgan to ask her why she "was being so weird about this?"

"I'm not being weird about this, Piers. I'm not running for office, I'm not promoting a legislative agenda. I'm promoting the policies that I lay out in the book that are mostly fiscal, that are mostly constitutional. That's why I agreed to come on your show. That's what I want to talk about. I'm not being weird; you're being a little rude," O'Donnell retaliated.

Morgan said that he was "being charming and respectful," at O'Donnell's insinuation of him being rude. He disagreed with O'Donnell when she said that he should only talk about the topics she agrees to: the ones in her book.

"These issues are in your book," Morgan says. An O'Donnell aide then stood in front of the camera and O'Donnell abruptly ended the interview saying, "yeah, OK, I'm being pulled away. We turned down another interview for this."

"Where are you going? You're leaving?" a baffled Morgan asked.

Trying his best to suppress chuckle, Morgan then wrapped up the show saying that the interview had just ended because he "had the audacity to ask questions based on stuff that's in this book."

"Anyway, it's a good book, it's called 'Troublemaker.' I think we know now why it's called 'Troublemaker,'" he added.

O'Donnell's Wednesday night walkout probably wasn't a publicity stunt and would probably leave her "embarrassed," Morgan told Broadcasting and Cable.

"Ms. O'Donnell wasn't happy about me quizzing her views on withcraft (sic) and sex. But really flipped at gay marriage Qs. Ripped mike and fled," Morgan tweeted shortly after the taping.

"My first ever walk-out in 25 years of interviews," Morgan continued. "I guess viewers can decide if I was 'rude' or not tonight at 9pm ET. #CNN"

The former Tea Party candidate garnered widespread media attention for her infamous "I'm You" campaign ad, where she denied accusations of witchcraft. During a "Good Morning America" appearance on Tuesday morning to promote her book, "Troublemaker," O'Donnell admitted she regretted the ad.

O'Donnell's book was released on Tuesday, and covers her 2010 campaign.
