Trump says Iran went back on allowing the U.S. to remove its highly enriched uranium

Trump claims that Iran told his administration that it would allow the U.S. to come in and help extract its highly enriched uranium but went back on that in its latest ceasefire proposal.

"They changed their mind because they didn't put it in the paper," he said.

Trump added that besides taking the uranium, the U.S. wants Iran to "guarantee no nuclear weapons for a very long period of time and a couple of other minor things, but they just can't get there. So they agree with us and then they take it back."

Iran has not publicly agreed to give up its enriched uranium and insists its nuclear program is peaceful.
