"We're still working on what they will be, but there's going to be a number of additional votes next week," he said in response to a question about whether the Senate could take up a resolution approving the agreement.
The House is planning such a vote this week in response to arguments from conservatives. The idea behind the vote is to put Democrats on the record as supporting the deal.
The Senate on Thursday is set to take a procedural vote on a resolution to reject the deal.
Clearing that hurdle requires 60 votes. Democrats are expected to have the 41 votes to block it, though Sen.

Congress has until Sept. 17 to pass legislation on the international accord, which would lift sanctions on Iran in exchange for limits on its nuclear program.
