President Donald Trump said on Monday that he fired Federal Reserve Governor Lisa Cook over alleged mortgage fraud. She vowed to keep her job.

President Trump has no authority to remov Governor Lisa Cook,” her lawyer, Abbe Lowell, said in a statement on Tuesday. “His attempt to fire her, based solely on a referral letter, lacks any factual or legal basis.

The president said in a letter posted on his Truth Social platform Monday night that he is removing Lisa Cook effective immediately.
