During the presidency of Donald Trump, the Office of Special Counsel, which is tasked with enforcing the Hatch Act, officially reported several of Trump's aides for ethics violations and called on the president to fire his senior counselor Kellyanne Conway for repeatedly ignoring the rules. It is up to the president to determine any appropriate disciplinary action for workers who violate the law, and Trump declined to take action against Conway or the others.
Trump took no action, so why should Biden?
