Trump said he held talks with European Commission President Ursula von der Leyen on a number of issues, including their shared position on the inadmissibility of Iran possessing nuclear weapons. The conversation also discussed the trade deal signed in Turnberry, which Trump called the largest trade agreement in history.

Trump said the EU had committed to zero tariffs as part of the agreement. He said he had given von der Leyen until July 4—the 250th anniversary of the United States—to fulfill the EU's commitments, warning that tariffs would increase sharply if the EU failed to comply.

The trade agreement reached at Trump's Scottish golf resort in July 2025 stipulated that the EU would eliminate tariffs on American manufactured goods, while the US would cap tariffs on most goods at 15 percent.

Negotiations between EU lawmakers and governments on implementing legislation for the deal ended on Wednesday without reaching an agreement. The European Commission, which leads trade negotiations on behalf of the bloc's 27 member states, has yet to adopt the necessary enabling legislation.

Trump had previously threatened to impose 25 percent tariffs on European cars.
