On March 7th, according to Axios, on the morning of the first digital assets summit day at the White House, Senator Elizabeth Warren sent a critical letter to the government's head of cryptocurrency and artificial intelligence, David Sacks, known as the crypto czar. Senator Warren believes that the deeper the federal government supports the blockchain industry, the more it will drive up the value of existing holders, which creates conflict of interest issues for officials who make these policies. The senator raised multiple pointed questions regarding potential conflicts of interest for DavidSacks and his colleagues. She also detailed a series of initiatives by the Trump administration that she said raised concerns about the ethics of its decision-making.
