Washington (CNN)Lawmakers have some homework for their summer break: deciding how they want to vote on the Iran nuclear deal. On Wednesday, President Barack Obama got confirmation from his 34th senator backing his proposal, which gave the President a veto-sustaining coalition that would ensure passage of the deal.
While the GOP-led Congress has scheduled action on legislation in September to block the deal, President Barack Obama has pledged to veto it. That means Republicans would have had to pick up 44 Democrats in the House and 13 in the Senate to reach the two-thirds majority needed to override a presidential veto -- assuming all Republicans are present and vote for it.
Here's where things stand now, of the Democratic lawmakers who have committed.
House Democrats who are a "no" on the deal (18 of 44 needed to override a potential veto):
Brad Ashford, Nebraska
Brendan Boyle, Pennsylvania
Ted Deutch, Florida
Eliot Engel, New York
Lois Frankel, Florida
Gene Green, Texas
Alcee Hastings, Florida
Steve Israel, New York
Dan Lipinski, Illinois
Nita Lowey, New York
Carolyn Maloney, New York
Grace Meng, New York
Donald Norcross, New Jersey
Kathleen Rice, New York
David Scott, Georgia
Brad Sherman, California

Note: 151 House Democrats signed a May letter supporting the then-unfinished Iran negotiations, though only 146 are voting members, and none have come out against the deal since it was completed.
