WASHINGTON (AP) — Mass layoffs and resignations at the federal government are prompting concerns that a disgruntled former employee may seek to sell secrets to a foreign power. National security experts say that while the overwhelming majority of federal workers are conscientious patriots who would never sell out their country, it would only take one or two informants to cause a significant national security crisis. Counterespionage is a concern even when the federal workforce is stable. But in recent weeks President Donald Trump and Elon Musk’s Department of Government Efficiency have slashed thousands of jobs. National security and intelligence experts say Russia, China and other adversaries will seek to take advantage of the opportunity.
