Republicans brought up the disapproval resolution on the Iran deal on a motion to proceed, and the motion fell two votes short of the 60 needed on a 58-42 vote.

Senate Democrats on Thursday blocked a Republican effort to scuttle the Iran nuclear deal, delivering the Obama administration a long-awaited, major foreign policy victory.

But with Republicans in both chambers dead set on taking further shots to eviscerate the deal, and potentially even dragging it to court to block its implementation, the Iran deal debate may not be over.

The vote on the procedural motion was 58 to 42, falling two votes short of the 60 votes  needed to consider the resolution attacking the agreement.

Stay tuned - Republicans immediately vowed to bring the disapproval resolution back for further votes next week.
