President Donald Trump pushed back on reports that the U.S. will be paying Iran millions as part of a ceasefire agreement in a post on Truth Social Monday.

“Iran has agreed to never have a Nuclear Weapon! Also, the story that the U.S. is paying Iran 300 million Dollars is Fake News, put out by the Dumocrats!!!” Trump wrote on his Truth Social account.

Earlier Monday, Vice President JD Vance said Iran could eventually gain access to a $300 billion reconstruction package under a deal brokered by the president, while insisting that no American taxpayer money would be used and that Tehran would  have to meet strict nuclear-related conditions.

Speaking on ABC's "Good Morning America," Vance pushed back on criticism of the agreement and rejected suggestions that the Trump administration was simply handing cash to the Iranian regime.

"Not one dollar is being transferred to Iran for signing this agreement," Vance said.

He said any sanctions relief or economic benefits would depend on Iran verifiably dismantling its highly enriched uranium stockpile and accepting international monitoring of its nuclear activities.

The vice president said Iran could eventually gain access to a package worth roughly $300 billion if it permanently abandons its pursuit of nuclear weapons.

"The $300 billion reconstruction package is not American money," Vance said.

Vance said the proposed funding would come from Gulf Arab nations that have a strong interest in preventing future wars and instability in the Middle East.

"We've offered them a path toward economic growth and integration with the world economy if they're willing to give up their nuclear weapons program," Vance said.
