(FILES) US Federal Reserve Board Chairman Jerome Powell speaks during a news conference following a Federal Open Market Committee (FOMC) meeting in Washington, DC, on December 10, 2025. A US federal judge has quashed subpoenas issued to the Federal Reserve as part of an investigation that Fed chair Jerome Powell has called an attempt by the Trump administration to intimidate the independent central bank. "A mountain of evidence suggests that the Government served these subpoenas on the Board to pressure its Chair into voting for lower interest rates or resigning," wrote Judge James Boasberg in a filing dated March 11, 2026.
