On the day of the first digital asset summit at the White House, Senator Elizabeth Warren sent an open letter to David Sacks, the encryption and AI affairs director of the Trump administration, questioning potential conflicts of interest and requesting relevant financial disclosure information. Warren believes that government intervention in the blockchain industry could drive up market prices, leading to conflicts of interest among policymakers. She requested that Sacks disclose the identities of individuals involved in formulating encryption reserve strategy decisions, and clarify whether they are subject to conflict of interest regulations. Warren questioned whether Sacks engaged in relevant transactions before the policy was enacted and requested proof of his divestment from personal encryption assets.
