WASHINGTON (AP) — President Donald Trump on Monday appeared to undercut a proposal that was offered by his special envoy to Iran, saying he will insist that Tehran fully dismantle its nuclear enrichment program as part of any deal to ease crushing sanctions.

The call comes as Trump has been trying to accelerate aid into Gaza and has been trying to persuade Iran to give up its nuclear program.

A US president who vowed to be a peacemaker has to handle a new Middle East crisis that strikes a blow to his diplomatic efforts.

The president had asked Israel to hold off. Now he’s scrambling to make a deal in negotiations that have become even more complex.

Israeli Prime Minister Benjamin Netanyahu said Sunday that Iran's Islamic regime targeted President Donald Trump for his efforts to thwart Iran's nuclear weapons program, and worked to assassinate him.

Secretary of State Marco Rubio was the first to respond to the attack publicly with a statement Thursday evening — but others have yet to comment.
