President Donald Trump’s negotiators face the arduous task of trying to convince the president that a deal he previously rejected is their best option in Iran.

Last month, Trump initially gave his blessing for a so-called “cash for uranium” deal, under which the US would release around $20 billion in frozen funds in exchange for Iran handing over its stockpile of highly enriched uranium, sources familiar with the matter tell WIRED.

Trump’s negotiators, vice president JD Vance, special envoy Steve Witkoff and Jared Kushner, Trump’s son in law, received repeated approvals from the president while they were in Islamabad, giving them confidence a deal was close.

But the deal unraveled, in part because Trump was warned by his team that there was a risk he could be seen as giving Iran “pallets of cash”—an echo of his own oft-stated criticism of Barack Obama’s Iran deal—and he pulled the plug, the sources said.

Except now, that’s once again the cornerstone of the current proposal.

The current negotiations for a memorandum of understanding that could guide talks on a nuclear deal center on Iran handing over its stockpile of highly enriched uranium, and a moratorium on further uranium enrichment for somewhere around 12 to 15 years, Axios earlier reported.

In exchange, the US would offer a combination of billions in sanctions relief and the gradual release of frozen funds after gaining control of the enriched uranium, in order to destroy it or blend it down so it cannot be used for a nuclear weapon.

While a memorandum of understanding might get Iran to the table, that framework is not materially different from what was discussed previously in Islamabad and rejected by Trump, who has repeatedly told advisers in recent weeks he is against sending money to Iran, sources tell WIRED.

Some of Trump’s advisers say the decision of whether Trump ultimately blesses the framework is likely to come down to how badly he wants a deal. There are few options to incentivize Iran, they add, and financial aid has been the most compelling.

“They are going to have to do something like that, and it’s better than the Obama deal, so he should take it,” one Trump adviser said on the condition of anonymity, referring to the Joint Comprehensive Plan of Action. Trump has long criticized that deal for having provisions similar to ones currently under discussion, like a sunset clause on nuclear enrichment and the US lifting some sanctions.

For all the machinations in the West Wing, it has not gone unnoticed by Trump’s orbit that some of his top players have been conspicuous in their absence on Iran, according to two administration officials familiar with the matter.

Marco Rubio, the secretary of state and national security adviser, has been part of the group advising Trump on Iran and, physically speaking, spends most of his time in his West Wing office overlooking West Executive Avenue instead of at the State Department.

Rubio was happy to brief reporters on Tuesday, but he only did so at the request of the White House, a person familiar with the matter said, with his advisers wary of him getting involved in Iran negotiations that could as easily unravel as succeed.

In fact, given the downside risk, Rubioworld has been saying they were surprised that Vance asked to be a part of the Iran talks—a contention denied by people close to the vice president, who said he was ordered to by Trump.

Rubio instead has been more focused on Cuba, and on Venezuela, where assistant secretary of state Caleb Orr has been involved in overseeing new private equity investment to rebuild the country’s oil infrastructure.

Vance has been stuck in an awkward middle ground. Vance is a good soldier and is regularly in the Situation Room, but he was always skeptical of striking Iran at all and once suggested a six-month delay to build up the US stockpile of anti-missile interceptors, according to a person familiar with the matter.

Instead, he got pulled into back-channeling with Iran on Trump’s orders. But, with Iran talks stalled, his focus is increasingly on the midterms, which are looking worse for Republicans by the day. Case in point: On Tuesday, Vance was out on the campaign trail in the Midwest and headlining a Republican National Committee fundraiser.
