McCance announced Thursday on CNN's "Anderson Cooper 360" that he would quit because of the condemnations that followed his comments.
McCance posted his remarks in reaction to a campaign asking people to wear purple Oct. 20 to show solidarity after several gay and lesbian youths killed themselves after they were bullied. McCance said the dead children "killed thereselves because of their sin."
McCance did not return a phone message left by the AP at his carpet cleaning business in Pleasant Plains, about 70 miles northeast of Little Rock.
