Louisiana Sen. David Vitter, whose telephone number was disclosed by the so-called "D.C. Madam" accused of running a prostitution ring, says he is sorry for a "serious sin" and that he has already made peace with his wife.

"This was a very serious sin in my past for which I am, of course, completely responsible," Vitter said Monday in a printed statement. "Several years ago, I asked for and received forgiveness from God and my wife in confession and marriage counseling. Out of respect for my family, I will keep my discussion of the matter there — with God and them. But I certainly offer my deep and sincere apologies to all I have disappointed and let down in any way."

"I don't believe there's any issue that's more important than this one...I think this debate is very healthy, and it's winning a lot of hearts and minds. I think we're going to show real progress."

Asked by an interviewer in 2000 whether she could forgive her husband if she learned he'd had an extramarital affair, as Hillary Clinton and Bob Livingston's wife had done, Wendy Vitter told the Times-Picayune: "I'm a lot more like Lorena Bobbitt than Hillary. If he does something like that, I'm walking away with one thing, and it's not alimony, trust me."
