Massachusetts Rep. Barney Frank challenged Newt Gingrich to a debate on the Defense of Marriage Act (DOMA) in his retirement speech.

DOMA, the law that bars federal agencies and the military from recognizing the legal marriages of gay and lesbian couples, became law in 1996 while Gingrich served as House speaker.

Citing redistricting concerns, Frank, the House's first openly gay member, on Monday announced he would not seek a seventeenth term in 2012.

Frank said he was looking forward to seeing Gingrich as the GOP nominee, then challenged him to a debate.

“I did not think I had lived a good enough life to be rewarded by Newt Gingrich being the Republican nominee. It still is unlikely, but I have hopes,” Frank told reporters. “Let me say, for example, I intend to continue to be an advocate of public policy. I look forward to debating, to take one important example, the Defense of Marriage Act with Mr. Gingrich. I think he is an ideal opponent for us, when we talk about just who it is, is threatening the sanctity of marriage.” (The video is embedded in the right panel of this page.
