The National Post reports in its Wednesday edition that more than 20 civil service employees resigned Tuesday from billionaire Trump adviser Elon Musk's Department of Government Efficiency, saying they were refusing to use their technical expertise to "dismantle critical public services." An Associated Press dispatch to the Post quotes the 21 staffers saying in a joint resignation letter: "We swore to serve the American people and uphold our oath to the Constitution across presidential administrations. However, it has become clear that we can no longer honor those commitments." The employees also warned that many of those enlisted by Mr. Musk to help him slash the size of the U.S. government were political ideologues who did not have necessary skills or experience. The mass resignation of engineers, data scientists and product managers is a temporary setback for Mr. Musk and Donald Trump's purge of the federal work force. The staffers who resigned worked for what was once known as the United States Digital Service, established during president Barack Obama's administration. All had previously held senior roles at such tech firms as Google and Amazon and said they joined the government out of a sense of patriotic duty.
