Senator Elizabeth Warren is demanding answers from David Sacks, Trump's AI and crypto czar, over whether he's violated federal rules by working beyond the 130-day limit for temporary government employees. The probe comes as Sacks shapes critical AI and cryptocurrency policy while reportedly splitting time between Washington and Silicon Valley to dodge duration restrictions.
The political heat is rising around David Sacks' unprecedented dual role as Trump's AI and crypto czar. What started as a temporary government assignment has now triggered a formal congressional investigation led by Senator Elizabeth Warren, who's demanding transparency about whether Sacks has blown past federal employment limits.
Warren, alongside Rep. Melanie Stansbury and seven other Democratic lawmakers, delivered a pointed letter Wednesday morning pressing Sacks to account for every single day he's worked since January. The lawmakers want to know where he's conducted official business and who's monitoring his compliance with the 130-day cap for Special Government Employees.
The timing couldn't be more sensitive. As the Trump administration moves to implement recently enacted cryptocurrency legislation and establish new AI governance frameworks, Sacks finds himself at the center of both policy areas worth trillions in market value. His influence extends from OpenAI partnerships to Bitcoin strategic reserves discussions.
Sacks came to the White House with serious financial skin in the game. According to White House disclosure documents, he sold over $200 million worth of digital asset investments through his venture firm Craft Ventures before taking the role. The massive divestiture underscored just how deeply embedded he was in the crypto ecosystem he now helps regulate.
But it's his work patterns that have caught Warren's attention. Reports from The SF Standard suggest Sacks has been strategically splitting time between Washington and Silicon Valley, potentially to avoid triggering the federal day count. Colleagues reportedly told Semafor he has "no intention of leaving" the role, despite its temporary designation.
The Special Government Employee category was designed to let private sector experts serve briefly in government under relaxed conflict-of-interest rules. Warren argues that stretching these boundaries undermines the careful balance Congress struck when creating the framework. "Overstaying the limit would raise additional ethics concerns," the lawmakers warned, particularly given the administration's aggressive crypto policy timeline.
The investigation has heavyweight backing. Bernie Sanders signed on, along with Democratic Senators Richard Blumenthal, Chris Van Hollen, and Jeff Merkley. Representatives Betty McCollum and Rashida Tlaib also joined the probe, signaling broad progressive concern about Trump's tech policy apparatus.
Sacks' position puts him at the intersection of two of the most politically charged tech sectors. His AI responsibilities span everything from Meta's algorithmic oversight to Google's search monopoly discussions, while his crypto mandate covers everything from stablecoin regulations to Bitcoin mining environmental standards.
The venture capitalist's background made him an unusual choice for government service. As a founding member of the PayPal Mafia alongside Elon Musk and Peter Thiel, Sacks built his reputation investing in companies like Airbnb and Uber before pivoting to crypto and AI startups through Craft Ventures.
Neither the White House nor Sacks responded to requests for comment about the investigation. The silence comes as crypto markets watch nervously for policy signals that could move billions in market cap overnight.
The Warren probe also connects to broader Democratic efforts to tighten ethics rules for temporary government advisors. Her previous legislation aimed at increasing transparency requirements for SGEs now looks prescient given the Sacks situation.
If the investigation finds Sacks exceeded his legal authority, it could trigger a broader review of how the Trump administration has used temporary appointments to place industry executives in key regulatory roles. The precedent would have implications far beyond crypto and AI policy.
Warren's investigation puts the spotlight on a fundamental tension in modern tech policy: how do you regulate industries when the experts come from the very companies they're supposed to oversee? Sacks' case tests whether temporary appointment rules can contain the revolving door between Silicon Valley and Washington, or whether they'll need a complete overhaul for the AI age.
