President Donald Trump on Thursday again denied reports that the United States would provide Iran with $300 billion as part of a postwar reconstruction fund as Washington and Tehran prepare to sign a memorandum of understanding aimed at formalizing a peace agreement.

"There is no 300 Billion Dollar payment to Iran by the U.S. That's Fake News! All there is for the U.S. is Success, Lower Oil Prices, and Victory. Check out the Stock Market. Dumocrat propaganda at play!!! President DJT," Trump wrote on Truth Social.

The president's comments marked the second time this week he has rejected reports surrounding the proposed reconstruction fund, which has become a focal point of debate as details of the agreement emerge.

A $300 billion reconstruction fund for Iran does exist, though Vice President JD Vance has said the money would come from the Gulf Coast Coalition, apparently referring to the Gulf Cooperation Council, which includes Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, and the United Arab Emirates.

Speaking from the White House briefing room Thursday, in a press conference airing live on Newsmax, Vance sought to clarify what he described as widespread media misunderstandings about the agreement, insisting that no U.S. taxpayer money would be sent to Iran.

"The United States isn't giving up a cent of money to Iran," Vance told reporters, adding that Iran would only gain access to reconstruction funding if it agrees to "fully comply" with the terms of the agreement.

"As you all know, the part of the peace plan, the part of this MOU that I think has been most misrepresented by certain parts of the media, is the idea that the Iranians get all these benefits," Vance said.

"You will hear things about $300 billion, or $24 billion, or this or that number or amount of money," the vice president added.

"The simple fact is that the only way the Iranians get any of those resources — not a single penny, by the way, from the United States of America under any circumstances — but the only way that they would ever get any benefit of the bargain is if they comply fully and change their behavior," Vance said.

He stressed that the agreement would benefit the United States regardless of whether Iran accepts its obligations.

"And so you really have a win-win situation for the United States of America. If the Iranians don't change their behavior, their military and their nuclear program are still destroyed," he said.

"If they do change their behavior, then they are going to have a transformative relationship with the Middle East, and the Middle East will have a transformative relationship with the people of Iran," he added.

Vance concluded Thursday's briefing with a criticism of media coverage surrounding the agreement.

"So what I'd ask all of you is just to report honestly that the United States isn't giving up a cent of money to Iran, and even the economic benefits, the sanctions relief, and so forth that comes along with this bargain, it only happens if the Iranians perform," he said.
