On March 7th, according to Axios, Senator Elizabeth Warren sent a critical letter to David Sacks, the government's cryptocurrency and artificial intelligence czar, during the morning of the White House's first digital assets summit day. Warren believes that the more the federal government supports the blockchain industry, the more it will raise the value of existing holders, creating conflicts of interest for the officials making these policies. The senator raised several sharp questions involving potential conflicts of interest for David Sacks and his colleagues. She also detailed a series of actions by the Trump administration, saying these actions have raised concerns about the ethics of their decision-making.
