According to Foresight News, Senator Elizabeth Warren, known for her critical stance on cryptocurrencies, has sent a letter to U.S. cryptocurrency and AI official David Sacks. The letter raises concerns about potential conflicts of interest involving Sacks and his associates. Warren has requested that Sacks disclose all reports he has submitted to the government ethics office and identify those involved in drafting the recently announced asset reserve list. She inquires about how many of these individuals are bound by conflict of interest laws and whether any engaged in related transactions before the policy's release.

The letter also highlights various initiatives under U.S. President Donald Trump's administration, which Warren claims have raised ethical concerns regarding decision-making in the industry.
