Bill Pulte, who runs the Federal Housing Finance Agency under President Donald Trump, confirmed Thursday that he filed a criminal referral against Federal Reserve Governor Lisa Cook for alleged mortgage fraud.

We partnered with Palantir at Fannie Mae,” Pulte said on Bloomberg Television. Pulte had urged Attorney General Pam Bondi to open a probe into Cook over a pair of mortgages allegedly claiming primary occupancy in a letter first reported by Bloomberg on Tuesday night.

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