WASHINGTON - US Senator John McCain said on Thursday that Republicans stood behind a letter to Iran's leaders threatening to undo any nuclear deal despite an outpouring of criticism from the White House, US allies and Democrats.
He said the Republican senators could have taken more time to talk about it, but he had no remorse.
"Maybe we should have had more discussion about it," McCain told Reuters. "I certainly think I should have signed it, and I think that the message needs to be sent."
The letter signed by 47 of the 54 Republican senators warned Iran that any nuclear deal made with President Barack Obama, a Democrat, could last only as long as he remained in office - a highly unusual intervention into U.S. foreign policy-making.
