Trump caps UK trip with $350B tech pact, heads to Arizona for Kirk’s memorial service

President Donald Trump spent the bulk of the week in the U.K. where he inked a new tech deal, and closed out the week gearing up to attend the memorial service of conservative activist Charlie Kirk in Arizona. 

During the trip abroad, Trump and U.K. Prime Minister Keir Starmer unveiled a new $350 billion tech investment plan, which is expected to generate 15,000 jobs across the U.K. and up to 2,500 jobs in the U.S. 

Specific details of the "Tech Prosperity Deal" are sparse, but officials said that the plan will invest in the development of 12 advanced nuclear reactors and that energy will go toward supplying energy needs for the U.K. and the U.S. 

"It's a blueprint to win this new era together. Shape it according to our shared values, and seize the incredible opportunities that are on offer," Starmer said. "We have huge new investments from Nvidia N scale, Open AI, Google, Salesforce and many more backing cutting-edge British jobs for years to come."

The plan will accumulate $50 billion in economic value and will deliver power to as many as 1.5 million homes, according to Trump. 

Trump also touted the close relationship between the U.S. and the U.K. during a state dinner at Windsor Castle with members of the U.K.’s royal family, including King Charles III. 

"His Majesty spoke eloquently about the bond which inspired Sir Winston Churchill — the bust is in the Oval Office right now — the beautiful bust of Winston Churchill, to coin the phrase ‘special relationship,’ but seen from American eyes, the word ‘special’ does not begin to do it justice," Trump said Wednesday. "We're joined by history and fate, by love and language and by transcendent ties of culture, tradition, ancestry and destiny."

Trump arrived back in Washington later Thursday and will leave for Kirk’s memorial service Sunday at State Farm Stadium in Glendale, Arizona. The venue holds 63,400 people and has the capacity for up to 73,000 for "mega-events," according to its website.

Kirk, 31, was killed during a stop on his American Comeback Tour Sept. 10 at Utah Valley University. Kirk’s death has also raised questions about Trump’s own security, amid two assassination attempts on Trump’s life in 2024. 

A senior administration official confirmed to Fox News Digital Friday that federal law enforcement agencies like the Department of Homeland Security released a report Thursday cautioning that they are monitoring "several threats of unknown credibility" against Trump, Vice President JD Vance and others expected to attend Kirk’s memorial service.

The assessment asserts that the memorial may be an attractive target for violent extremists or lone wolf actors due to the significant media coverage it's expected to attract.

Meanwhile, Trump said he likely will share some remarks during the memorial service. 

"It's going to be big," Trump told reporters Monday. "I'm going to be at the stadium, and I guess I'll say a few words. I don't know, but I guess I will, but I knew him very well. He was an amazing guy. He was all about young people and getting them started."
