Former Delaware U.S. Senate candidate Christine O’Donnell stormed off the set of "Piers Morgan Tonight" Wednesday, apparently in objection to the CNN host's questions about gay marriage.
When asked why she's skirting the topic, O'Donnell responded, "I don't think it's relevant. It's not a topic that I chose to embrace, it's not what I'm championing right now -- I've been there, done that, gone down that road."
Morgan pushed O'Donnell further, asking why she is being "so weird about this."
"I’m not being weird, you’re being a little rude," O'Donnell said to the host, right before storming off the program's set.
"Ask the candidates who are running for office what they think."
O'Donnell said that she chose to arrive late for a talk with the Republican Women's Club so she could discuss her book on CNN, "not to endure a rude talk show host."
On Twitter, Morgan expressed surprise by O'Donnell's reaction.
"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 became a late-night punchline after her "I'm You" campaign ad, where she denied accusions of witchcraft. During a "Good Morning America" appearance Tuesday morning to promote promote her book, "Troublemaker," O'Donnell admitted she regrets the now-famous ad.
"Trust your gut," O'Donnell said. "Trust your instincts."
O'Donnell's book was released Tuesday, and covers her 2010 campaign.
A spokesperson for O'Donnell did not immediately respond to TheWrap's request for comment.
