Outgoing New Hampshire Rep. Charles Bass on Thursday became the third House Republican to support repeal of the Defense of Marriage Act (DOMA), the 1996 law which prevents federal agencies from recognizing the marriages of gay and lesbian couples.

According to gay glossy The Advocate, Democratic New York Rep. Jerrold Nadler announced that Bass had signed on as a co-sponsor to his measure, known as the Respect for Marriage Act.

“I'm thrilled that Rep. Charlie Bass will be our newest GOP co-sponsor of the Respect for Marriage Act to repeal DOMA,” Nadler said in a statement. “Rep. Bass is the second Republican in the past week to endorse equal protection for all Americans. Though he won't be continuing his service in the next Congress, his commitment to equality and ending discrimination is truly appreciated.”

Last week, New York Rep. Richard Hanna announced his support for the bill. Florida Rep. Ileana Ros-Lehtinen is a longtime supporter.

Representative-elect Ann McLane Kuster, the Democrat who unseated Bass, supports marriage equality.

With a constitutional challenge to DOMA headed to the Supreme Court, Nadler has previously argued that his bill remains relevant. That's because even if the court strikes down the law, the ruling would only affect states which have extended marriage rights to gay and lesbian couples. Nadler's bill would repeal the measure and guarantee that the federal government would recognize all legal marriages. That is, a gay couple's Connecticut marriage would be recognized by the federal government even if they moved to Ohio, where such unions are not legal.
