Christine O'Donnell stormed off the set of the "Piers Morgan Tonight Show" Wednesday, upset over questions about gay marriage. The former Delaware U.S. Senate candidate and Tea Party member walked off the CNN set when Morgan asked her about views on sexual abstinence and gay marriage.

"I'm not talking about policies," she told Morgan. "I'm not running for office. Ask Michele Bachmann what she thinks."

O'Donnell went on the show to promote Tea Party principles she outlines in her new book, "Troublemaker: Let's Do What It Takes to Make America Great Again." The book was published on Tuesday by St. Martin's Press. It is currently ranked 2,228 on Amazon's bestsellers rank.

Readers have given O'Donnell's book a three out of five star rating so far.

"Christine is merely a self promoting individual who looks attractive, speaks pretty well, but has no real intellect," wrote one reviewer.

When O'Donnell ran as a Tea Party candidate in 2010 for the Senate seat vacated by Joe Biden she was dubbed "Tea Party Darling" and "Troublemaker" by Time and a leader of the "Second American Revolution" by foreign press. During the campaign she came under media scrutiny for an "I'm You" campaign ad, in which she said she wasn't a witch.

"I'm not a witch," she said, "I'm you."

On the show to promote her book, Morgan asked her when she declined to answer the questions about abstinence and gay marriage if she was being "weird."

O'Donnell shot back: "I'm not being weird. You're being a little rude."

"Don't you think as a host, if I say this is what I want to talk about, that's what we should address?"

O'Donnell then removed her microphone and ended the interview.

"I was supposed to be speaking at the Republican Women's Club at six," she said, "and I chose to be a little late for that. Not to endure a rude talk show host, but to talk to you about my book and the issues I address in my book."

Morgan tweeted a response to O'Donnell's walk off shortly after the show's taping concluded.

"Ms. O'Donnell wasn't happy about me quizzing her reviews on witchcraft and sex. But really flipped at gay marriage Qs. Ripped mike and fled," he wrote. "My first ever walk-out in 25 years of interviews. I guess viewers can decide if I was 'rude' or not tonight at 9pm ET. #CNN."
