ROLL CALL: Questions Over Iran Jam Leaders, Defense Bill Negotiators. “An interim deal with Iran on its nuclear program is complicating the future for the annual defense authorization bill, as Senate Majority Leader Harry Reid, D-Nev., must manage three clashing factions: senators intent on passing a new round of sanctions, a White House that opposes them and armed services negotiators who simply want to see their bill passed. Republicans hellbent on attaching Iran sanctions to the pending defense authorization bill froze Senate action before Thanksgiving, and the Senate is scheduled for only one more week of work before Christmas. The Iran agreement has only brought more voices into the fold, with Democrats such as Sen. Charles E. Schumer of New York and Senate Foreign Relations Chairman Robert Menendez of New Jersey, calling for new sanctions legislation.”
