Facing heavy pressure from President Obama, Senate Democrats on Tuesday signaled they have reservations about moving forward with Iran sanctions legislation.
Some senators who had previously backed a sanctions bill treaded carefully when asked whether they support holding a vote on legislation before the Iran talks wrap up in June.
"Well let's wait and see when there's a bill. There's no bill yet," said Sen.

"Let's wait and see how the whole thing plays out."
"I don't have a sense that there's anything that will happen in the near term," Casey added.

The Senate banking committee had scheduled a hearing for Tuesday to debate and vote on sanctions, but postponed the session until next week, with outside opponents of the bill citing a lack of bipartisan support.
A spokeswoman for Sen. Richard Shelby (R-Ala.), the panel’s chairman, said the hearings were "rescheduled to give senators more time."

Brown said he wants to see what administration officials have to say at a classified briefing on Iran next week.
"I want to hear the briefings before I commit for sure on Menendez-Kirk," he said.
The White House is pushing Senate Democrats to withhold their support, arguing passage has the potential to end the chances for reaching a historic diplomatic accord with Iran.
Obama last week threatened to veto the bill if it reaches his desk, and spoke with Senate Democrats about the issue behind closed doors.

"The administration has a point. I think we should listen to what they have to say, and hopefully we can reach some agreement on when's the best timing for its consideration," he said.

Without the support of at least 13 Democrats, the sanction bill will not reach a veto-proof majority of 67 votes. Last year, 17 Democrats, including Menendez, cosponsored the bill, but five of them lost reelection in November.
Menendez isn’t backing down, and told The Hill he would introduce his bill when he's "ready."

Richard BlumenthalRichard BlumenthalOvernight Healthcare: Biden hints at new money for cancer research | Trump details opioid plan | Dem urges feds to reject EpiPen settlement Dem calls on DOJ to reject EpiPen settlement Why Yahoo's breach could turn the SEC into a cybersecurity tiger MORE (D-Conn.) said he would discuss the Iran bill with Menendez and other colleagues on Tuesday and throughout the week.
"I think that the principles and convictions incorporated in the bill are significant and they deserve a hearing. The question of timing is one we need to discuss," he said.
Other Democrats played down dissension in the caucus, saying there is broad agreement that if no deal is reached, Iran should pay the price.
"We all want the same thing. We want a non-nuclear Iran, and we prefer to get there diplomatically rather than by any other outcome. So this is really a question of strategy rather than end-goal," said Sen.

Kaine, who did not support the previous Menendez-Kirk bill, said he is looking at the new version because it is "different from the previous one."
Still, the senators said he fears a new sanctions bill could shift the focus away from Iran's behavior.
"And I don't want to do anything that makes people question whether we are negotiating fairly," he said.
