Sen. Bob Corker (R-Tenn.) said Sunday he believes the Senate is very close to ending a logjam over confirming Loretta Lynch as the next attorney general. "My sense is over the next 48 to 72 hours that is going to be resolved, and we'll move on to this Iran issue," he said on CNN's "State of the Union." Lynch was nominated in November to replace Attorney General Eric Holder, but a vote on her confirmation has been put off time and again.
