After 47 Republican senators signed an open letter warning Iran that its nuclear deal with the United States would not be upheld after President Obama left office, pundits and politicians alike weighed in on the issue.
The Council of Guardians from The Islamic Republic of Iran responded to the letter. "Prompted by your letter, our council has decided to end the talks with your secretary of state and dismiss nuclear inspectors from our country," the response reads.
Ayatollah Ali Khamenei, Iran's supreme leader, also responded to the letter, saying the “backstabbing” that characterizes American politics worries him.
"US senators officially announce that when this government leaves, its commitments will become nullified," he said. "Isn't that the ultimate collapse of political ethics and the disintegration of the US system?"
President Obama briefly responded to the letter shortly after it was published on March 9.
In a new interview with Vice, Obama shared his thoughts on the matter.
"I'm embarrassed for them,” he said. "For them to address a letter to the ayatollah - the supreme leader of Iran, who they claim is our mortal enemy - and their basic argument to them is: don't deal with our president, because you can't trust him to follow through on an agreement ... That's close to unprecedented.”
The deal, which international politicians hope will be closed soon, seeks to limit the amount of uranium Iran can enrich in exchange for reducing the economic sanctions against the Middle Eastern country.
The U.S., along with the U.K., France, Germany, Russia and China, are working on the deal with Iran.
