CNN’s Don Lemon let loose Monday in a lengthy rant aimed at his own colleague, CNN political commentator Rick Santorum, in response to comments he made concerning the country’s founding. The left-wing host blasted the former Pennsylvania senator for saying in an April speech to the Young America’s Foundation that the United States was founded by Europeans looking for religious freedom, and that there wasn’t much Native American culture within American culture. He also claimed Santorum’s comments were offensive to Native Americans, used the phrase “Native American lives matter,” and seemingly called for his conservative colleague to be fired.
