Federal Housing Finance Agency Director Bill Pulte suggested Thursday that his referral of Federal Reserve Governor Lisa Cook for alleged mortgage fraud was part of a broader crackdown on the issue.

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.

President Trump called on Fed Governor Lisa Cook to resign on Wednesday after one of his appointees accused her of mortgage fraud.
