Bill Keller, a right-wing televangelist who frequently goes on rants against Mormonism and homosexuality, told a caller on his “Live Prayer” show to commit suicide.

Keller, who has worked with conservative activists including Janet Porter and Rick Wiles, told the viewer that he should think about suicide and that “it might help the world.”

Video of Keller’s comments was posted by a number of YouTube users today. The viewer’s comments to Keller are inaudible. Keller later denied making the claim and said suicide is a sin.
