President Trump signed the US-Iran memorandum of understanding on Wednesday over dinner at the Palace of Versailles in France.
A video of the signing at a candlelit table shows Trump autographing the deal with his signature black Sharpie-style marker with French President Macron and Secretary of State Marco Rubio at his side. Dinner guests applaud his signing, and Trump is seen giving out the markers as mementos — as he often does at White House executive order events.
“A pretty key moment in history we are sharing together,” Rubio said.
President Trump on Wednesday signed a copy of the US-Iran memorandum of understanding by hand over dinner with French President Macron.
The agreement would end the three-month war against Iran and begin 60 days of tough nuclear negotiations.
Trump had witnessed Vice President JD Vance sign the document electronically on Sunday, a senior US official confirmed to The Post, but this was now Trump’s turn to seal the deal.
“On Sunday, the MOU was signed digitally by Vice President Vance and [Iranian Parliament] Speaker [Mohammad-Bagher] Ghalibaf and witnessed by President Trump,” the person said. “Now, it has been signed by President Trump and President Pezeshkian.”
US officials have previously said Trump also electronically signed the document on Sunday.
The original plan was for the MOU to be physically signed in-person by Vance — and potentially Trump — with Iranian senior officials during a ceremony in Switzerland on Friday, which Iranian Foreign Ministry spokesman Esmail Baghaei said has since been canceled.
The president previously signed the document electronically with Iran on Sunday.
The US official did not respond to a question requesting confirmation that the ceremony was no longer happening.

Baghaei said the president of Iran would also sign it Wednesday, after which “violating it will carry a higher cost.”

“As of now, plans for the negotiating teams to be present in Geneva remain in place, but the memorandum has been signed digitally and no signing ceremony will be held in Switzerland,” he told reporters. “The text of the Iran-U.S. memorandum is now officially finalized, because both sides have signed it.”
A senior US official telegraphed earlier Wednesday that the Switzerland event was in doubt, that signing could occur “remotely.”

The official said that the question now is whether Iran will make the necessary concessions in nuclear negotiations to warrant a final deal.
If they fail to do so, the official said the US would strengthen economic punishments and potentially re-establish the blockade on Iranian ports — which is now lifted with the president’s signature on the document.
