"I think it's somewhat ironic to see some members of Congress wanting to make common cause with the hardliners in Iran. It's an unusual coalition," Obama told reporters.
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.
Iran's Zarif blasted the Republicans. "I wish to enlighten the authors that if the next administration revokes any agreement 'with the stroke of a pen' ... it will have simply committed a blatant violation of international law," he said in a statement.
