In an interview on 'Fox and Friends,' U.S. Senator Lindsey Graham (R-South Carolina) criticized the nuclear deal reached by Iran and six world powers led by the United States.

Graham said: "What the president has done is he’s taken the world's most destabilizing power, one of our chief antagonists, a country that's killed hundreds of Americans in Iraq and he’s guaranteed that they're going to become a nuclear nation.

"Instead of dismantling their program, this deal locks in their nuclear program."
