Senators on Wednesday took the first step toward a vote on the Iran nuclear deal.

The chamber will turn to the legislation when it reconvenes in September.
After the August recess, senators will have less than two weeks to vote on the Iran deal before the Sept. 17 deadline. 
"The debate we're going to have in a matter of weeks, I want it to be … dignified," he said. 
A senior Democratic aide suggested that senators were reaching an agreement on proceeding to the Iran legislation on Sept. 8 "due to the intense time crunch" that month. The aide added that McConnell "cannot afford to be on any bill besides Iran when the Senate reconvenes."
The procedural step on Iran legislation comes amid growing support for the deal from Senate Democrats.

Still, many Senate Democrats are undecided, and opponents of the deal intend to pressure them over the recess.
So far no Senate Democrat has said publicly that they will vote against the deal. President Obama will need the support of at least 34 Senate Democrats to sustain the expected veto of the Iran bill.
