Though the five-paragraph letter is addressed to leaders in Tehran, it seems as much aimed at delivering a message to Obama.
Republicans and some Democrats want Congress to vote on any agreement. The pact the bargainers are working on does not require congressional approval because it is not a treaty, which would require a two-thirds majority Senate vote to be ratified.
Last week, Senate Majority Leader Mitch McConnell, R-Ky., postponed action on legislation that would give Congress a vote on any deal that emerges. He delayed the measure in the face of solid Democratic opposition to moving ahead on the bill now, just weeks before an end-of-March deadline for negotiators to produce an outline of an agreement.
On CBS’ “Face the Nation” Sunday, McConnell said the president would need congressional approval to lift sanctions already imposed on Tehran because of its nuclear program.
“I think he cannot work around Congress forever,” McConnell said.
Obama said in a separate CBS interview that the U.S. would “walk away” from the talks unless they produce a procedure for verifying that restrictions on Iran’s nuclear effort are working.
The letter released Monday was signed by 47 of the Senate’s 54 Republicans. Included were McConnell and the rest of the Senate GOP leadership plus presidential contenders Marco Rubio of Florida, Rand Paul of Kentucky and Ted Cruz of Texas.
The next negotiations are scheduled for March 15, and wide gaps remain between the two sides.
Iran has said its nuclear program is peaceful and is aimed at producing energy.
There was no immediate Iranian government reaction to the letter or any discussion of it in Iranian media.
