A U.S. federal appeals court on Monday rejected President Donald Trump's attempt to swiftly remove Federal Reserve governor Lisa Cook, according to local media reports.

The 2-1 ruling Monday by a panel of the U.S. Court of Appeals for the District of Columbia Circuit stated there was "no need" at this stage of the case for the appeals court to decide whether the allegations against Cook meet the "for cause" standard to dismiss a Fed governor.

This means the Trump administration has only hours to bring the case to the Supreme Court, as the Fed's critical interest rate meeting will start Tuesday morning. Without a Supreme Court decision, Cook will be able to attend and vote at the Federal Open Market Committee meeting on Tuesday and Wednesday.

A federal judge on September 9 blocked Trump's removal of Cook and ruled she must be immediately reinstated.

Also on Monday, the U.S. Senate confirmed Stephen Miran, one of Trump's top economic advisers, to serve on the Federal Reserve's governing board in a 48-47 vote, succeeding Adriana Kugler, who resigned from the board in early August. Miran is expected to serve through Kugler's remaining term, which ends in January.

Miran plans to continue his role as chair of the White House's Council of Economic Advisers while taking unpaid leave, reports said.
