A member of the Federal Reserve’s Board of Governors announced Friday that she is resigning several months before the end of her term, handing President Donald Trump an early opportunity to fill a key vacancy.

Trump has launched a series of scathing attacks on Powell over his refusal to reduce interest rates. The president claimed that the central banker is "TOO ANGRY, TOO STUPID, & TOO POLITICAL, to have the job of Fed Chair" in a post on his Truth Social website on Thursday.

A bubbling movement to overhaul the Fed is ready to seize the moment. Big changes are in store for the central bank.
