President-elect Donald Trump is arriving at the White House armed with a legal weapon that will let him fire any of President Joe Biden’s appointees.

Thanks in part to a court fight former Trump White House spokesman Sean Spicer lost over his firing by Biden from a three-year term to the Board of Visitors to the United States Naval Academy, the incoming president will have the legal backing to dump any of Biden’s over 4,000 appointments who try to stick around.
