Trump reveals Iran made 'significant proposal' after ultimatum, but 'not good enough'

President Donald Trump said Iran negotiators made "a significant proposal, a significant step," following the ultimatum he issued on Easter Sunday, but it is not "good enough."

"They made a proposal, and it's a significant proposal, a significant step," Trump told reporters at the Easter Egg Roll on Monday, a White House tradition that comes amid the backdrop of war.

"It's not good enough, but it's a very significant step," Trump continued. "They are negotiating now. And they have made a very significant step. We'll see what happens."
