May 8 (UPI) -- President Donald Trump threatened to raise tariffs to "much higher levels" on the European Union if it doesn't agree to a trade deal by July 4.

"I had a great call with The President of the European Commission, Ursula von der Leyen. We discussed many topics, including that we are completely united that Iran can never have a Nuclear Weapon. We agreed that a regime that kills its own people cannot control a bomb that can kill millions. I've been waiting patiently for the EU to fulfill their side of the Historic Trade Deal we agreed in Turnberry, Scotland, the largest Trade Deal, ever! A promise was made that the EU would deliver their side of the Deal and, as per Agreement, cut their Tariffs to ZERO! I agreed to give her until our Country's 250th Birthday or, unfortunately, their Tariffs would immediately jump to much higher levels," the president said Thursday afternoon on Truth Social.

The threat came after The EU has struggled to agree on the terms of the Turnberry Accord, which was for the United States to lower tariffs on EU products and for the EU to remove tariffs on U.S. industrial goods and invest billions in U.S. industries, including energy.

Von Der Leyen said on X that the bloc is still committed to the deal.
