Sen. John Ensign (R-Nev.) has admitted to having an extramarital affair with an also-married woman. Today he issued the following statement:

I came home to Nevada to come forward and explain to the citizens of our state something that I was involved in about a year ago. Last year I had an affair. I violated the vows of my marriage. It is the worst thing I have ever done in my life. If there was ever anything in my life that I could take back, this would be it. “I take full responsibility for my actions. “I know that I have deeply hurt and disappointed my wife Darlene, my children, my family, my friends, my staff and others who believed in me. To all of them, especially my wife, I am deeply sorry. I am truly blessed to have a wife who has forgiven me. We sought counseling last year and have built a stronger marriage — stronger than ever. “I will not mention any names but the woman who I was involved with and her husband were close friends and both of them worked for me. Our families were close. That closeness put me into situations which led to my inappropriate behavior. We caused deep pain to both families and for that I am sorry. “I am committed to my service in the United States Senate and my work on behalf of the people of NV. “Thank you.

Ensign’s wife also issued a statement saying that she loves her husband and that they have come to a reconciliation. The New York Times reports that Ensign is an evangelical Christian and actively involved in Promise Keepers.

UPDATE: Ensign has resigned as chairman of the Republican Policy Committee, the fourth-ranking spot in GOP Senate leadership.
