Santorum discusses pro-marriage pledge with Candy Crowley

Republican presidential candidate Rick Santorum was initially “taken aback” by a pro-marriage pledge that asks presidential candidates to promise personal fidelity to their spouses, but said he ultimately decided to sign it. “When I first read it, I was taken aback by it. I can’t argue that I wasn’t,” the former Pennsylvania senator said in an interview airing Sunday on CNN’s “State of the Union.”
