From his home office in small-town Kentucky, a seasoned political operative is quietly investigating scores of federal employees suspected of being hostile to the policies of Republican Donald Trump, an effort that dovetails with broader conservative preparations for a new White House.

Tom Jones and his American Accountability Foundation are digging into the backgrounds, social media posts and commentary of key high-ranking government employees, starting with the Department of Homeland Security. They are relying in part on tips from his network of conservative contacts, including even workers themselves. In a move that alarms some, they are preparing to publish the findings online.

With a $100,000 grant from the influential Heritage Foundation, the goal is to post 100 names of government workers to a website this summer to show a potential new administration who might be standing in the way of a second-term Trump agenda — and ripe for scrutiny, reclassifications, reassignments or firings.
