U.S. President Donald Trump signed an agreement with Iran on Wednesday requiring dilution of Tehran's highly enriched uranium stockpile in exchange for waived U.S. sanctions, with Pakistani Prime Minister Shehbaz Sharif as mediator. White House deputy chief of staff Dan Scavino shared video of the signing, which followed weekend digital signatures by Trump and Vice President JD Vance. Reports conflict on whether the physical signing occurred at the Palace of Versailles during a dinner with French President Emmanuel Macron.
