Native American activists are calling on CNN to fire commentator and former Republican Senator Rick Santorum over remarks he made to an ultra-conservative student conference.

Rick Santorum: “We came here and created a blank slate. We birthed a nation from nothing. I mean, there was nothing here. I mean, yes, we have Native Americans, but, candidly, that — there isn’t much Native American culture in American culture.”

The National Congress of American Indians criticized CNN for not firing Santorum. The group’s president, Fawn Sharp, said, “Televising someone with his views on Native American genocide is fundamentally no different than putting an outright Nazi on television to justify the Holocaust.”
