Local time on December 22, the U.S. president-elect Trump announced the nomination of Michael Kratsios as the next director of the White House Office of Science and Technology Policy (OSTP). Kratsios served as the Chief Technology Officer of the White House during Trump's first term and was also the Deputy Secretary of Defense responsible for Research and Engineering at the Pentagon. He graduated from Princeton University and is also a distinguished fellow at Stanford University. AI and crypto czar David Sacks commented on this on X: "This appointment is well-deserved. Michael has been with the OSTP for four years during Trump's first administration and knows it inside out. We have spent countless hours discussing technology policy. Now, we will collaborate on these ideas under President Trump's leadership. It is very exciting!" Earlier, David Sacks denied reports of a role change on the X platform: "Some traditional media reported tonight that my role has changed, which is completely wrong. I expect to spend half my time in Washington guiding policy and half my time in Silicon Valley." Earlier, Fortune reported that sources within the transition team revealed that the position had been downgraded from a leadership role to a general advisory role last week, partly because Sacks was unwilling to part ways with the investment firm Craft Ventures and did not want to go through the formal appointment process. In the future, Michael Kratsios will lead technology policy work, and Sacks will provide policy ideas. Despite the change in position, Sacks remains influential, often active in Florida and San Francisco, and meets with lawmakers. His appointment has sparked controversy over conflicts of interest, but some in Silicon Valley are optimistic, believing it may help startups, although some have doubts about his expertise and are concerned about the direction of policy.
