UK Prime Minister Keir Starmer was not at the Oval Office for the trade deal announcement but joined it via a speaker phone.

Starmer did not provide any more details, which he said they needed to hammer out, but praised Trump for their countries' partnership.

"I think it is a real tribute to the history that we have of working so closely together," he said.

"We finalized it and built an incredible platform for the future," the prime minister added.

Trump announced a trade deal with the United Kingdom, but was scant on details.

"Both countries agreed the economic security is national security and we'll work together as allies to insure that we have a strong industrial base, appropriate export controls and protections for key technologies and industries like steel," he said.

The House voted to codify President Donald Trump’s Gulf of America executive order by a vote of 211-206. Rep. Don Bacon of Nebraska was the only Republican to vote against the measure.

The bill heads to the Senate where its future is uncertain since bipartisan support is required, and Leader John Thune has not indicated whether he’ll put the measure on the floor for a vote.

Beyond the committee chairs managing the floor debate, Rep. Marjorie Taylor Greene – flanked by a map labeling the Gulf of Mexico as the Gulf of America – was the only Republican to speak in support of the legislation.

Meanwhile, several Democrats, including Leader Hakeem Jeffries “strongly” urged lawmakers to vote against “this small-minded, silly and sycophantic bill” during floor debate.

“Republicans have decided to spend this entire legislative day doing is to debate a bill to rename the Gulf of Mexico. Now, in some ways the American people can be thankful,” Jeffries added.

As Trump is slated to announce his trade deal with the U.K., the British economy found itself in a different situation over the tariffs than other nations.

Dozens of nations face potential so-called "reciprocal tariffs," but the U.K. is not among them, since the U.K buys more than it sells to the U.S.

The White House paused the reciprocal tariffs until July, as it seeks to strike trade agreements with dozens of countries.

The country, however, was still hit with Trump's baseline 10% tariff issued for almost all foreign nations.
