We knew the fight to keep Iran-focused diplomacy alive wasn't over - and we were right. Just before the Senate went home for the holidays, Senators Menendez (D-NJ), Kirk (R-IL) and a group of 25 colleagues introduced a new and highly problematic Iran sanctions bill in the Senate - S. 1881, ironically named the "Nuclear Weapon Free Iran Act of 2013." Over the holiday break, this bill was the focal point of a major lobbying effort, with AIPAC and other groups working intensively to get Senators to cosponsor the measure -- and this effort will pick up additional steam in the coming days.

• Urge your Senators to refuse to cosponsor S. 1881 and to oppose efforts to bring this outrageous bill to the floor for a vote.
