Chris Murphy, the senior senator from Connecticut, said it does not appear the United States has actually reached a ceasefire agreement with Iran, since both countries are sharing different terms of the agreement. But, if the agreement that Iran believes it has entered into is true, that would be “cataclysmic for the world”.

In an appearance on CNN shortly after Donald Trump announced the ceasefire in a social media post, Murphy said: “Who knows what’s going on. Donald Trump lies every single day.”

But Murphy raised concerns about Iran’s explanation of the 10-point plan it shared with the United States, which suggests the strait of Hormuz would be regulated “under the coordination of the Armed Forces of Iran.”

Murphy added that the Iranian National Security Council claims “that Trump has also agreed to Iran’s right to enrichment, to suspend all sanctions against Iran, and to allow Iran to keep their missile program, their drone program and their nuclear program.”

“Now, who knows if any of that is true, but if, at the very least, this agreement gives Iran the right to control the strait that is cataclysmic for the world, and it is just stunning that that’s where we have gotten to that Donald Trump took a military action that has apparently, at least for the time being, given Iran control over a critical waterway that they did not have control over, before the war began.”

In a separate reaction to the ceasefire agreement, Senate minority leader Chuck Schumer said: “I’m glad Trump backed off and is desperately searching for any sort of exit ramp from his ridiculous bluster.”
