A federal judge put the brakes on the Justice Department’s criminal probe of the Federal Reserve, saying it was part of an improper campaign by the Trump administration to pressure the central bank into cutting interest rates more aggressively.

Judge James Boasberg quashed subpoenas that had been issued to the Fed in January, ostensibly seeking information about cost overruns on the renovation of the Fed’s headquarters. At the time, Fed chairman Jerome Powell had called that a pretext. And Judge Boasberg agreed.

“The Government has offered no evidence whatsoever that Powell committed any crime other than displeasing the President,” Boasberg writes in a newly-unsealed opinion. “There is abundant evidence that the subpoenas’ dominant (if not sole) purpose is to harass and pressure Powell either to yield to the President or to resign and make way for a Fed Chair who will.”
