(Reuters) – Republican U.S. senators warned Iran’s leaders on Monday that any nuclear deal with President Barack Obama could last only as long as he remains in office, an unusual partisan intervention into foreign policy that could undermine delicate international talks with Tehran.

The open letter was signed by 47 senators, all but seven of the Republicans in the Senate, and none of Obama’s fellow Democrats, who called it a “stunt.” It says Congress plays a role in ratifying international agreements and points out that Obama will leave office in January 2017.

They said they would consider any deal merely “an executive agreement” if it is not approved by Congress.

“The next president could revoke such an executive agreement with the stroke of a pen and future Congresses could modify the terms of the agreement at any time,” the letter read.

A White House spokesman called the letter a continuation of a partisan strategy seeking to undermine Obama’s ability to conduct foreign policy. He said it “certainly interferes” in efforts to negotiate a nuclear deal with Iran.

The Iranian Students’ News Agency quoted Foreign Minister Javad Zarif as saying: “It is propaganda and has no legal value … Change of the government does not mean cancellation of that country’s international legal obligations.”

A Western diplomat said the action was “without precedent.” “It’s 100 percent an American issue, but obviously it could become a real problem,” the diplomat said.

The letter angered Senate Democrats.

“This is a cynical effort by Republican senators to undermine sensitive international negotiations. It weakens America’s hand and highlights our political divisions to the rest of the world,” said Richard Durbin, the Senate’s number two Democrat.

The letter, first reported by Bloomberg, was the latest Republican effort to influence the Iran talks. Many Republicans worry Obama is so eager for a deal he will sign off on an agreement leaving Iran able to easily make a nuclear weapon.
