Sen. Bob Corker, R-Tenn., hammered Secretary of State John Kerry Wednesday, telling the former chairman of the Senate Foreign Relations Committee the administration is “exercising the worst judgement possible” in handling the threat posed by ISIS. “Do you realize how unserious, the things that you have laid out and the things that were laid out yesterday, sound?” Corker said. “You’re asking us to approve something that we know, the way you’ve laid it out, makes no sense. … It seems like a political answer.”
