Federal Reserve Mounts Closed-Door Fight Against Justice Department Subpoenas
U.S. Attorney Jeanine Pirro is investigating testimony Chair Jerome Powell provided last summer around building renovations, a probe he has called improper
WASHINGTON—The Federal Reserve is waging a behind-closed-doors legal challenge to a pair of subpoenas issued as part of U.S. Attorney Jeanine Pirro’s criminal investigation into Chair Jerome Powell, according to people familiar with the matter.
Pirro, a longtime ally of President Trump, opened the probe to examine whether Powell gave false testimony to Congress last summer about the central bank’s building-renovation project. The move prompted an unprecedented public response from Powell, who in a Jan. 11 video statement said the investigation was a pretext for Trump’s continuing campaign to pressure the Fed to lower interest rates and end the independence of the central bank.
There is evidence Mr. Pool exaggerates.
