Rachel Maddow has criticized “ex-gay” activist Richard Cohen for denying he had a hand in crafting Uganda's anti-gay bill.

Cohen last year disavowed parts of his book Coming Out Straight on Maddow's MSBNC show The Rachel Maddow Show.

Cohen, the founder of the International Healing Foundation, claims to have converted the sexual orientation of himself and thousands of others. He is a former president of Parents and Friends of Ex-Gays and Gays, a group that believes gay people can and should be “cured” of their homosexuality.

In promoting the bill which would increase the penalties for gay sex in Uganda to include execution under certain instances, lawmakers cited Cohen's work.

During the segment, Maddow grilled Cohen about a passage in his book in which he wrote “40 percent of molestation assaults were made by those who engage in homosexuality.” Cohen quickly retracted the statement, saying the passage would not appear in the next edition of the book.

During an interview with NPR's Fresh Air, host Terry Gross asked Maddow about the incident.

“To have somebody disavowing the reason why they're there talking to me in the first place, their complicity in this thing that they're denying any responsibility for, it doesn't bother me as a gay person – it bothers me as a rational human being. It bothers me as somebody who wants accountability and who is grossed out by people who shirk their responsibility,” Maddow told Gross.
