San Francisco 49ers quarterback Colin Kaepernick may be more concerned about the welfare of the Islamic State than his country, according to a Republican congressman.

“This is activism that is sympathetic to ISIS,” Rep. Steve King told Newsmax host Steve Malzberg on Tuesday. “I think Colin Kaepernick is representing the San Francisco 49ers when he puts on that uniform. When he steps out on the stage, the world stage, he’s taking advantage of that and he’s undermining patriotism.”
