Ken Mehlman, former chairman of the Republican National Committee and the former campaign manager for George W. Bush's 2004 re-election bid, has told his family and colleagues that he is gay, according to The Atlantic's Marc Ambinder.

From Ambinder's report:

"It's taken me 43 years to get comfortable with this part of my life," Mehlman said. "Everybody has their own path to travel, their own journey, and for me, over the past few months, I've told my family, friends, former colleagues, and current colleagues, and they've been wonderful and supportive. The process has been something that's made me a happier and better person. It's something I wish I had done years ago."

Mehlman, who headed the RNC from 2005 to 2007, becomes the highest-profile national Republican figure to come out as gay.

In the interview, Mehlman said that he reached the decision to come out in part because he would like to play a greater role as an advocate for same-sex marriage.

He added that earlier this year, he participated in a fundraiser for the American Foundation for Equal Rights, an organization that has fought the Proposition 8 ballot initiative banning same-sex marriage in California. An appeals court ruled earlier this month that the ban will stay in place until December, overruling a federal judge's decision that the ban was unconstitutional.
