In its first foreign policy challenge to President Barack Obama, the Senate is likely to vote soon on legislation restricting the administration's ability to strike a deal with Iran over its nuclear program, officials attending a retreat of Republican lawmakers said Thursday.
Sen. Bob Corker, the new chairman of the Foreign Relations Committee, said he and other lawmakers are drafting a measure to give Congress a right to "vote up or down" on any agreement, a prerogative it currently does not have.
The new Congress is now controlled in both chambers by Republicans.
