Army Sergeant Darren Manzella, who spoke to Leslie Stahl on 60 Minutes, has been discharged from the Army, reports the Servicemembers Legal Defense Network (SLDN), a pro-gay group working to repeal Don't Ask, Don't Tell – the military's policy that bans gays from serving openly.

Manzella participated in a December 2007 story for the CBS news magazine 60 Minutes where he revealed he had been openly out to his superiors without incident.

In the news piece, Manzella says he was investigated for being gay and even supplied the Army with photos of his boyfriend - A.J. - and a video of the pair kissing during a road trip. But when the investigation ended he was told to go back to work.

Manzella said the Army found “no evidence of homosexuality.”

The SLDN reports Manzella was discharged under Don't Ask, Don't Tell effective June 10th.

The sergeant enlisted in the U.S. Army in 2002 and was twice deployed to the Middle East in support of Operation Iraqi Freedom. He was awarded the Combat Medical Badge for providing medical care under fire during the Iraq war.

The SLDN reports that a growing number of gay and lesbian service members are serving openly without incident. The organization says it is aware of more than 500 troops who are serving openly.

“The discharge of battle-tested, talented service members like Sergeant Manzella weakens our military in a time of war. National security requires that Congress lift the ban on gays in the military and allow commanders to judge troops on their qualifications, not their sexuality,” said Adam Ebbin, Communications Director of SLDN.

“My sexual orientation certainly didn't make a difference when I treated injuries and saved lives in the streets of Baghdad. It shouldn't be a factor in allowing me to continue to serve,” said Manzella.
