Bill Pulte — a private equity executive and social media philanthropist — has quickly become an outspoken fixture in the Trump administration’s efforts to overhaul the central bank and use a little-known agency to investigate perceived enemies.

Bill Pulte, the director of the Federal Housing Finance Agency, has accused Fed governor Lisa Cook of mortgage fraud again. Shortly after 9:30 a.m. on Friday, the Trump appointee posted what he described as “new evidence in the Cook matter” on his X account.

The surprise early resignation of former Fed Governor Adriana Kugler, another Biden pick, gives Trump an early opening to nominate someone to the central bank’s board and steer its monetary policy trajectory more toward his preferred path. He has named one of his economic aides, Stephen Miran, to fill the slot on an interim basis.
