Former House Speaker Newt Gingrich denied that he was guilty of hypocrisy for leading the charge to impeach President Bill Clinton while carrying on an affair of his own during Fox News Sunday.

Gingrich acknowledged cheating on his first two wives and said he was obviously doing things he wasn't proud of, but said he drew the line at lying under oath during his divorce proceedings. He said the real issue at stake in the impeachment was whether a popular president should have to obey the law.

"I don't think the president of the United States can be above the law," Gingrich said. "And it's not about personal behavior. It's about whether -- it's not about what he did in the Oval Office," he said, once again arguing Clinton committed perjury.

Gingrich admitted to host Chris Wallace that he felt like a man in a glass house during the events, but said it didn't deter him from pressing forward with what he viewed as his responsibilities.

"I thought to myself if I cannot do what I have to do as a public leader, I would have resigned," Gingrich said.

Wallace said many people view Newt's attempted explanations of his infidelities as "lame."

"But let me explain why. You love your country and you're working hard. And so you strayed. That wouldn't work with my wife," Wallace said.

"No, it didn't work in my life," Gingrich replied. "I went on to say that I had to seek God's forgiveness and I had to seek reconciliation and I had to believe that being genuinely repentant mattered."

Gingrich said he was confident the American people would judge him fairly if he runs for president despite his past mistakes.

"I expect the American people in the end will be remarkably fair," he said. "They'll render judgment and they'll decide whether or not Newt Gingrich is somebody that they think can solve the country's problems and be the kind of leader they want for this country."

Gingrich also denied accusations he has flip-flopped on Libya, arguing that his recent statements have come in response to President Obama's shifting stance on military intervention there. He said the president should make it clear that Gadhafi's removal is a vital part of any U.S. actions there.
