Senator Elizabeth Warren and seven other Democratic congresspeople have sent a joint letter to David Sacks, President Trump's 'Crypto and AI Czar,' questioning whether he has exceeded the 130-day service limit for Special Government Employees (SGEs). The lawmakers' investigation suggests Sacks may have reached his 167th day of service as of September 17, 2025, far beyond the legal limit.
The letter emphasizes that Sacks' ability to maintain his private-sector position as general partner at Craft Ventures—which holds stakes in multiple crypto companies—while serving in government depends entirely on his temporary SGE status. If he has exceeded the 130-day limit, his continued receipt of private salary would constitute an ethical violation. The lawmakers noted: "Compliance with the SGE time limit is critical, given the scale of your conflicts of interest."
According to their calculations, Sacks' 130th day of service would have been May 29, 2025, if working every calendar day since the January 20 inauguration, or July 25 if counting only business days. The letter demands full accounting of his service days, which are not publicly disclosed.
