Massachusetts Senator Scott Brown will be honored by gay GOP group Log Cabin Republicans for backing repeal of “Don't Ask, Don't Tell,” the policy set to expire on September 20 that bans gay and bisexual troops from serving openly.

“Senator Brown knew that 'Don't Ask, Don't Tell' was not working and was a critical part of the legislative team that ended the policy,” said Log Cabin Republicans Executive Director R. Clarke Cooper.

Brown will receive the group's Spirit of Lincoln Award at a September 20 fundraiser in Washington, D.C.

“As I said when I voted to repeal 'Don't Ask, Don't Tell,' when a soldier answers the call to serve and risks life or limb, it has never mattered to me whether they are gay or straight,” Brown said in a statement thanking the group for the honor. “My only concern has been whether their service and sacrifice is with pride and honor.”

Brown, a tea party favorite, was among the eight Republicans who voted in favor of repealing the law in December, but his record on gay rights remains spotty.

While he's said that he believes the issue of marriage equality is “settled law” in his home state of Massachusetts, the senator has yet to co-sponsor a bill that would repeal the Defense of Marriage Act (DOMA), which bars federal agencies from recognizing the legal marriages of gay couples, despite the fact that Massachusetts has filed a lawsuit challenging the constitutionality of the law.
