Brian Carroll on Thursday announced his bid for a Colorado House seat, making him the first openly gay service member on active duty to run for elected office.

Carroll served two tours in Afghanistan and one in Iraq with Army Special Forces Information Management, Special Operations Command. He continues to serve in the Colorado National Guard.

“As far as I know I am the first out veteran and active national guardsman in the country to officially run for office since the repeal of 'Don't Ask, Don't Tell,'” Carroll said in a statement.

“Don't Ask, Don't Tell” was repealed on September 20. The law for 18 years banned gay and bisexual troops from serving openly.

“Ultimately, what this comes down to, I believe, is standing up and providing an opportunity for leadership,” Carroll told The Huffington Post. “Really, the repeal of 'Don't Ask, Don't Tell' provides that opportunity – not only for myself, but for so many other openly gay members of the military. This really is a historic moment, and I think the people are going to look back at this, and say, 'This is history in the making. This is when the entire ballgame changed.'”

Metro Weekly's Chris Geidner notes that Carroll is not the first openly gay veteran to run for elected office. Anthony Woods, an Army veteran who served in Iraq, ran for Congress in 2009. And in1999, Republican Steve May came out to colleagues and constituents during a speech on the floor of the Arizona statehouse where he served. The active duty Army reservist was allowed to finish his term.
