Federal Reserve Chair Jerome Powell said the U.S. Department of Justice served subpoenas on the central bank over building renovation matters ahead of his June 2025 Senate Banking Committee testimony. The subpoenas, according to Powell, warned of a possible criminal indictment tied to issues expected to arise during the hearing. He did not identify specific projects, individuals, or statutes under review. The Justice Department has not publicly detailed the investigation, and no charges have been announced. Lawmakers plan to question Powell on monetary policy, internal operations, and oversight of renovation contracts at Fed facilities.
