Michael Bussee, who helped co-found the “ex-gay” ministry Exodus International, says he was trying to fix his sexuality.

Bussee and Gary Cooper left the group they helped build, revealing that they were in love. Tragically, Cooper later died from an AIDS-related illness.

Bussee was among those interviewed for an Our America profile on the world's largest “ex-gay” group.

The episode aired Thursday, the day after Exodus announced that it was closing its doors after nearly 40 years and the group's president, Alan Chambers, apologized to the gay community.

“It started when I was a little boy; when I first realized that being gay was something you were supposed to be ashamed of,” Bussee told host Lisa Ling. “And going to the library when I was 12 and trying to find books on how to fix it. Then starting an organization that tried to fix it.”

Bussee said that in 1976 he belonged to the Anaheim, California-based megachurch Melodyland, which was part of the Charismatic Movement.

“They really believed in miracle healings and spontaneous deliverance and things like that. If people could be set free from other things, why not be set free from homosexuality and become straight?” he asked.

After Bussee's departure Exodus continued to grow, spreading its message that gay men and lesbians can – and should – alter their sexuality. Last year, Chambers reversed course, saying that such therapies do not work. (The video is embedded on this page. Visit our video library for more videos.)
