The president says he is firing Lisa Cook for alleged mortgage fraud but she argues he has no cause or authority to do so.
President Trump says he is firing a governor of the US central bank, a move seen as intensifying his bid for control over the setting of interest rates.
He posted a letter on his Truth Social platform on Monday night declaring that Lisa Cook – the first black woman to be appointed a Federal Reserve governor – was to be removed from her post on alleged mortgage fraud grounds.
She has responded, insisting he has no authority over her job and vowed to continue in the role, threatening a legal battle that could potentially go all the way to the Supreme Court.
The president’s threat is significant as he has consistently demanded that the central bank cut interest rates to help boost the US economy. Growth has sagged since he returned to office on the back of US trade war gloom and hiring has slowed sharply in more recent months.
Mr Trump has previously directed his ire over rates at Jay Powell, the chair of the Federal Reserve, blaming him for the economic jitters and has repeatedly called for him to be fired.
