The US Supreme Court says it will hear arguments in January over US President Donald Trump's attempt to remove Federal Reserve governor Lisa Cook, leaving her in the post for now. Cook sued Trump in August after the president announced he would remove her. "President Trump lawfully removed Lisa Cook for cause from the Federal Reserve Board of Governors. We look forward to ultimate victory after presenting our oral arguments before the Supreme Court in January," White House spokesman Kush Desai said. But in Cook's case, the court opted to hear arguments first before deciding the Justice Department's request to similarly remove Cook on a preliminary basis.
