Elizabeth Warren, ranking member of the U.S. Senate Committee on Banking, Housing and Urban Affairs, and Andy Kim, ranking member of its National Security and International Trade and Finance Subcommittee, issued a statement arguing that the Trump Administration’s failure to update export control regulations over the past year and a half may have allowed the most advanced U.S. artificial intelligence chips to flow to companies headquartered in China, potentially supporting China’s military capabilities. They said the Commerce Department could close the loophole immediately by issuing clear and comprehensive guidance, and called for Secretary Howard Lutnick to testify before the Senate Banking Committee over what they described as mismanagement of the Bureau of Industry and Security and the resulting national security risk.
