The U.S. Justice Department will not reopen its criminal investigation into former Federal Reserve Chair Jerome Powell, Attorney General Todd Blanche said, closing the matter without further legal action. The case centered on cost overruns and oversight of renovations at the Federal Reserve's headquarters, where an inspector general review found no grounds for a criminal referral or administrative misconduct but identified significant management and oversight weaknesses. The announcement supersedes earlier indications that the department could continue scrutinizing the project, ending speculation about renewed legal action against Powell.
