A federal judge blocked the Justice Department on Friday from enforcing subpoenas issued against Federal Reserve Chairman Jerome Powell, ruling the government failed to show any legitimate basis for the demands.

U.S. District Judge James Boasberg quashed two subpoenas served on the Federal Reserve’s Board of Governors that sought records related to a $2.5 billion renovation project at the central bank’s headquarters, a matter Powell testified about before Congress last year. The DOJ had opened an inquiry in November into whether Powell made false statements to lawmakers about the project’s cost.
