Trump says Iran's latest proposal reneges on giving up enriched material: 'Are they stupid people?'

The latest Iranian proposal reneged on a past vow to give up enriched uranium, according to Trump.

"They said you're going to have to take it: We were going to go with them," Trump said. "But they changed their mind because they didn't put it in the paper.

Trump said the U.S. would not accept any arrangement that leaves Iran with a path to a nuclear weapon.

"It's unbelievably weak," Trump said. "After reading that piece of garbage they sent us. I didn't even finish reading it. "I'm not going to waste my time reading it."

"I would say the ceasefire is on massive life support, where the doctor walks in and says, 'Sir, your loved one has approximately a 1% chance of living,'" he added.

Trump said his position remains unchanged: "Iran can not have a nuclear weapon. They're very dangerous. They're very volatile."

Some Iranian officials want a deal, but hard-liners are blocking an agreement, according to Trump.
