On December 22 local time, U.S. President-elect Donald 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 previously the Deputy Secretary of Defense 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 X: 'This appointment is well-deserved. Michael has served for four years in Trump's first administration and knows OSTP inside and out. We have spent countless hours discussing technology policy. Now, we will collaborate on these ideas under President Trump's leadership. It's very exciting!' Previously, 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 false. I expect to spend half my time in Washington guiding policy and the other half in Silicon Valley.' Earlier, Fortune reported that insiders from the transition team revealed that the position was downgraded from a leadership role to a general advisory role last week, partly because Sacks was unwilling to step away from his investment firm, Craft Ventures, and did not want to go through the formal appointment process. In the future, Michael Kratsios will lead the technology policy efforts, while Sacks will provide policy ideas. Despite the change in position, Sacks remains influential, often active in Florida and San Francisco, and meeting with lawmakers. His appointment has sparked controversy over conflicts of interest, but some in Silicon Valley are optimistic, believing it may benefit startups, although there are concerns about his expertise and worries about policy direction.
