Where Does Congress Stand on the Iran Deal?

Following a 60-day review period, Congress weighed in on a joint resolution either approving or disapproving the final deal on Iran’s nuclear program.

Where Does Congress Stand on the Iran Deal?

Following a 60-day review period, Congress weighed in on a joint resolution and approved the final deal on Iran’s nuclear program. BPC’s Iran Tracker kept tabs on the stance of every member of the House and Senate. BPC also broke down the finer points of the complex processes and procedures that govern a major decision like this one.


If Congress votes to disapprove, and a presidential veto follows, Congress will have to hold another vote on whether to override the veto, which requires two-thirds majority in both chambers.

The following are the key numbers to watch for when Congress votes:

First round218 votes required in the House to pass a resolution of disapproval (or approval); 60 votes required in the Senate to overcome a procedural hurdle before voting on the actual resolution, which would then require 51 votes to pass.

Second round: If Congress passes a resolution of disapproval, it will go to President Obama who has said he will veto it.

Third round: Congress will then have 10 days to hold a vote to override President Obama’s veto. A congressional veto override requires 290 House votes and 67 Senate votes.​ Which means the president would need 146 House votes or 34 Senate votes to sustain his veto and allow for approval of the deal, assuming all members vote.
