President Donald Trump claimed Friday he “most likely” will not fire Federal Reserve Chair Jerome Powell, despite persistently goading him to leave his post. Trump has publicly criticized the Fed chair for months for keeping interest rates steady despite the president’s insistence that Powell lower them.

Former President Donald Trump promised to lower interest rates if reelected. But the Fed, which sets the key rate, operates independently from the White House.
