A top evangelical leader has resigned his post following an uproar over a recent interview when he said he supports civil unions for gays.

The National Association of Evangelicals says the Rev. Richard Cizik quit Thursday as the group's representative in Washington.

The announcement follows Cizik's Dec. 2 interview on National Public Radio's "Fresh Air" program. Cizik said on the show that he backs same-sex civil unions and made other comments that the evangelical group says don't reflect their values.

Cizik had already made enemies of some evangelical leaders because of his high-profile fight against global warming.
