The Republican-controlled Congress apparently won't be able to vote down the Obama administration’s legacy-defining Iran nuclear deal, as four more Democratic senators announced their support Tuesday.
On Tuesday morning, Sens. Ron Wyden of Oregon, Richard Blumenthal of Connecticut, and Gary Peters of Michigan brought those in favor of the deal to 41 senators. And Tuesday evening, Sen. Maria Cantwell said she would also back it, bringing the total to 42. That's just enough to block a resolution of disapproval, which is expected to be voted upon with a 60-vote threshold—either to invoke cloture or to pass the measure—in the next week or so, maybe even on Sept. 11, a date that Senate Majority Whip John Cornyn tweeted would be “ironic.”
On Tuesday, Senate Majority Leader Mitch McConnell invited every senator to come to the chamber floor to debate the deal Wednesday afternoon.
The administration had already reached enough congressional support to override a potential veto and implement the deal, which limits the Iran nuclear program for at least a decade in return for granting sanctions relief worth billions of dollars. A resolution of disapproval would imperil the deal by barring the administration from lifting congressional sanctions. It also would, according to deal opponents such as the pro-Israel lobby AIPAC, scare off investors interested in Iran.
