I am deeply humbled and honored by @realDonaldTrump’s announcement that he will nominate me to serve as the next U.S. Ambassador to the Kingdom of Denmark. Representing our great nation abroad is a profound responsibility. I know first-hand the power of diplomacy to advance American interests and strengthen alliances, and I am grateful for the opportunity to return to Europe to promote the President’s agenda. I look forward to working with the dedicated teams at U.S. Embassy Copenhagen and U.S. Consulate Nuuk in Greenland to deepen the bonds between our countries. 🇺🇸🤝🇩🇰

I couldn’t be more grateful for @realDonaldTrump ‘s nomination to serve our nation as Under Secretary of Defense for Research and Engineering. It is a dream come true and I can’t wait to get started as part of @PeteHegseth ‘s leadership team. Our best days are yet to come!

Thank you, Mr. President. I am deeply honored and humbled by the trust that you have placed in me. President Trump’s historic landslide election gave new hope and strength to the American people and was a reminder that brighter days are ahead — both at home and abroad. On November 5, the world witnessed a movement that only Donald Trump could inspire—a once-in-a-generation political realignment uniting Americans of every background around a shared vision: that we can once again live in pride, peace, and prosperity. A guiding lesson from my time in the technology industry and as Commissioner on the @USCC_GOV is that the economic is strategic, and the strategic is economic. President @realdonaldtrump and @JDVance have laid out an aggressive agenda to face the twin convulsions of technological and geopolitical change, and ensure America wins the economic contests that define this century. The State Department will play a critical role in acting on this vision. I look forward to earning the support of the U.S. Senate and working with @MarcoRubio to implement President Trump's agenda. Now is the time to make history and MAKE AMERICA GREAT AGAIN.

Donald Trump has named David Sacks the "White House AI and Crypto Czar" It's time to build.

I’m extremely honored to be nominated by @realDonaldTrump and excited to support @RobertKennedyJr and the great people of @HHSGov to make America healthy again.

Exowatt launches today! ☀️ The power requirements to scale AI are astronomical. Within a decade AI will require 650TWh of new power generation – more than the electricity demand of South Korea. In the U.S. alone, data centers will require the equivalent amount of electricity to power 40 million households by 2030. Exowatt P3s can generate electricity at scale at just a $0.04 LCOE and with entirely renewable tech. That’s lower than the cost of most fossil fuels and doesn’t account for subsidies. We have already amassed a 1.2 GW backlog, worth $Bs from the mega tech hyperscalers, energy and data center companies. The system works by capturing the sun’s energy in the form of heat, storing it in a heat battery and converting it to electricity via a heat engine even when the sun is no longer out. This changes the economics of solar by solving a problem called the “Duck Curve” where all conventional solar producers are forced to sell their power at the same time while at maximum output, driving the electricity cost sometimes to zero or negative intraday and leaving no supply at night. Data centers need to operate 24/7 and typically have 60% of their OPEX from energy costs, so an inexpensive and ever available alternative is very important to them. Data centers are straining to bring capacity online and without solutions like Exowatt, are being forced to turn to fossil fuels like coal, oil and natural gas. We hope you’ll join us in pushing forward an abundant and non fossil fuel powered future!⚡️ bloomberg.com/news/articles/…
