Though many senators have made public demands for new sanctions on Iran, the effort in the chamber has been fractured by an apparent committee turf war and members offering competing proposals.
Even if senators were able to coalesce around a single proposal, Senate Majority Leader Harry Reid, D-Nev., and negotiators on a defense bill have cut off the opportunity to amend it.
Technically, the Senate Banking Committee has jurisdiction over sanctions legislation. Chairman Tim Johnson, D-S.D., said last week he would be working on his own framework, after initially indicating he would not draft a bill in light of the multilateral agreement between Western powers and Iran on the country’s nuclear program.
Those with Foreign Relations Committee ties are working on their own bills as well. Senate Foreign Relations Chairman Robert Menendez, D-N.J., is working with Illinois Republican Mark S. Kirk, while Sen. Lindsey Graham, R-S.C., is working with John McCain, R-Ariz., and others.
