President Joe Biden ordered the measure of respect following Carter's death for 30 days ‒ the prescribed federal timeframe for lowering flags after a president's death since 1954. Trump will be sworn in as the 47th president on Jan.

Trump has referenced the 39th president on multiple occasions, including on the latter's 100th birthday in October at a rally in Waunakee, Wisconsin. After calling Biden the worst U.S. president in history, he said that "Jimmy Carter is the happiest man because Jimmy Carter is considered a brilliant president by comparison."

Under President Joe Biden’s proclamation, flags will be at half-staff until a week after Trump’s Jan. 20 inauguration. Since ordering the flags lowered is a proclamation that a sitting president makes, Trump won’t be able to do anything about it until after he is inaugurated.
