Antony Blinken actually said...

"the President has been clear that the United States will do what it must to prevent Iran from acquiring a nuclear weapon."

"the Americans who are detained illegally, erroneously, wrongly by Iran need to be released irrespective of these negotiations"

"Does any program that Iran has at the end of this--at the end of any agreement, does it allow it as a practical matter to break out to get enough material for a nuclear weapon?"

"I think it is absolutely vital that we remain in close consultation with you as the negotiations proceed."
