Senate Democrats on Tuesday backed down from a confrontation with President Obama over new Iran sanctions, agreeing to withhold support if Republicans bring legislation to the floor.
But the Democrats warned Obama they will only hold the line against the bill for roughly two months, after which point they would be ready to join with Republicans to muscle it through.

The new deadline allows Menendez and the other Democrats to support the legislation while honoring the wishes of Obama, who has warned that sanctions could derail the negotiations over Iran’s nuclear program and pave the way to a military confrontation.
A senior administration official traveling with the president aboard Air Force One said the move to delay the sanctions vote is seen by the White House as a” very constructive signal."
March 24 was already the date that negotiators had set for reaching a political framework for an agreement, with the overall talks set to conclude June 30.
The sanctions bill, which Menendez is co-sponsoring with Sen.

But Republicans are eager to have the Iran debate, believing they have the upper hand by standing firm against Obama’s foreign policy and Iran’s nuclear ambitions.

“I think it has been heartbreaking to see how few Democrats, even to this day, are willing to stand up to the Obama administration when it comes to the threat of Iran acquiring nuclear weapons capability,” he said.
The March 24 deadline from Menendez sets the stage for a last-ditch push to try to reach the outlines of a deal.
In his letter, Menendez noted that the legislation would allow the president to waive additional sanctions for a month at a time to provide additional flexibility in the negotiations.
The Senate Banking Committee is planning to vote on the bill Thursday, and an aide to Menendez said he plans to co-sponsor and vote for it.
Schumer, another member of the committee, is also likely to vote for the bill. He said Tuesday he would co-sponsor it.
If the 10 Democrats were to vote for a sanctions bill on the floor, Republicans would be close to a veto-proof majority of 67. Only three additional Democrats would be needed.
