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

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.

"No American thinks it is appropriate that she serve during this time with a cloud hanging over her,” Ed Martin wrote in a letter to the Fed chair.

On Wednesday, Trump called on Cook to resign after Federal Housing Finance Authority director William Pulte sent a "criminal referral" to Attorney General Pam Bondi, accusing Cook of mortgage fraud. Neither Bondi nor the Justice Department has announced if they plan to open a criminal investigation into Cook.
