Today, I’m proud to share the release of @ENERGY’s finalized Fusion Science & Technology Roadmap. Developed with input from industry, National Labs, & academia, it sets a unified national strategy to move fusion from breakthrough to deployment. Read here: energy.gov/articles/energy-d…

The Presidential AI Challenge brought together young Americans from across the country to create AI tools to serve their communities. Today, the @WhiteHouse welcomed students, educators, and parents to celebrate this year’s National Champions!

“You are our future.” Melania Trump congratulated the first Presidential AI Challenge winners at the White House, calling the students “the best of America.” The contest brought together young innovators using AI to tackle real-world community challenges.

.@mkratsios47: "The purpose of this national competition was simple — to bring young Americans from across the country together in using AI tools to improve the lives of their communities... Our competitors in this historic challenge produced more than 2,500 projects aiming to overcome some of their communities' greatest challenges."

Today we kicked off the final round of the Presidential AI Challenge, welcoming finalists from across the country to D.C. Thank you @EDSecMcMahon, @ENERGY D/Sec Danly, @DepSecVaden, & @NSF A/Director Stone. Good luck to our finalists & see you all at the @WhiteHouse tomorrow!

Tomorrow, over 120 students, educators, and mentors from across the country will join the @WhiteHouse ceremony honoring Regional and National champions of the Presidential AI Challenge 🇺🇸

Was thrilled to host the U.S. National Physics Team at the @WhiteHouse this week with @USCTO47. These young geniuses represent the best of American ingenuity, and they are exactly why the future of science and technology leadership in this country is so bright.

Today, @POTUS signed a National Security Presidential Memorandum on AI in the national security enterprise. The men and women who defend our nation deserve the best, most secure, and most reliable AI in the world, and our citizens deserve to know it is handled responsibly with the care and seriousness they expect. The NSPM accelerates AI adoption from multiple vendors to prevent single points of failure, updates @DeptofWar’s guidance on autonomy in weapons systems to keep pace with the frontier, and ensures no entity can disable or degrade an AI system our warfighters depend on without prior approval. Under @POTUS’s leadership, we are putting our AI dominance to work to defend the American people.

For the first time in 40 years, America celebrates a CRITICAL milestone in nuclear energy ⚡️ @AntaresNuclear’s advanced reactor is the first of multiple anticipated to go critical by the July 4th deadline set by @POTUS. America’s nuclear renaissance is just getting started.

America answers the call. President Trump challenged us to deliver advanced reactors by our 250th anniversary, and today we’re already crossing a historic milestone — the first commercial non-light-water reactor gone critical in the U.S. in more than 40 years. This is what American ingenuity and determination look like. The nuclear renaissance is here.

Proud to announce Japan as the first international partner of the Genesis Mission! 🇺🇸🇯🇵 Together, we are investing $1B to accelerate scientific discovery through next-generation AI and advanced computing. A milestone moment for two long-standing partners.

NEW: Chairman @BrendanCarrFCC Proposes to Accelerate the Buildout of Secure Submarine Cable Infrastructure Rule Implements Goals of @POTUS’ AI Action Plan and America First Investment Policy Memorandum 🇺🇸 Read more 🧵⬇️

🚨 NEW: 🇺🇸 and 🇯🇵 announce new partnership to accelerate scientific breakthroughs and harness AI as a tool for discovery energy.gov/articles/united-s…

Lazy and inaccurate reporting from @NYT on this policy. The EO creates a process for frontier labs to voluntarily share cutting-edge cyber models in order to secure critical infrastructure and strengthen the government’s own cyber defenses. We are NOT conducting oversight of all new models, as that level of government overreach would have chilling effects on free speech and innovation.

Today @POTUS signed an EO that keeps America leading in AI while putting frontier AI capabilities to work strengthening our cyber defenses. AI systems are now the most powerful tools we have ever had to harden our cyber infrastructure and stay ahead of adversaries. It is a real blessing that these capabilities are being developed by American industry, and not by those who would use them against us. whitehouse.gov/presidential-…

🚨WATCH: THE FUTURE OF AVIATION IS TAKING OFF🚨 It was an honor to become the first U.S. Transportation Secretary to fly in an eVTOL🇺🇸 Now we’re taking the future of flight to the next level with projects across 26 states that include testing of: 
✅ Urban air taxis
✅ Emergency medical flights
✅ Regional travel 
 America will WIN the race for the next generation of aviation @BETA_aircraft @FAANews 🦅

Director @mkratsios47 led the U.S. delegation to the @G7 Digital and Technology Ministerial hosted by France. From advancing AI adoption, to protecting kids online, to unleashing energy abundance for the next wave of innovation, the Trump Administration is delivering results that strengthen our economy and keep America at the forefront of global tech leadership 🇺🇸

Thank you @ALehenanff for hosting a successful @G7 Digital and Technology Ministerial Meeting in Paris. Together we advanced important discussions on secure AI adoption, protecting children online, and unleashing the energy abundance needed to power the next generation of technological innovation. The United States remains committed to working with our partners to unlock the benefits of emerging technologies for our citizens and economies.
