The new chairman of the U.S. Senate Foreign Relations Committee said on Thursday he expected a bill addressing Iran's nuclear program to come to the U.S. Senate floor for debate ahead of a vote in early February, if not sooner."I think sometime toward the end of January or the first part of February, you'll see something being debated on the Senate floor," Republican Senator Bob Corker told reporters at a retreat for Republican lawmakers in Hershey, Pennsylvania.Corker told Reuters in an interview on Wednesday that Republican and Democratic lawmakers were pushing ahead with two pieces of legislation. One would impose more sanctions on Iran if international negotiators fail to reach an agreement by the end of June, and the other would let lawmakers weigh in on any final agreement reached by negotiators.Iran and six world powers have renewed their quest for an elusive nuclear deal - seen as crucial to reducing the risk of a wider Middle East war - after negotiators failed for the second time in November to meet a self-imposed deadline.
