Despite denials from a senior Trump administration official, secret watchlists of Americans are being used by federal agencies to track and categorize US citizens—especially protesters, activists, and critics of law enforcement—as “domestic terrorists,” investigative journalist Ken Klippenstein reported Wednesday. “Slipstream is a classified social media repository. “There’s just one problem: She’s lying,” wrote Klippenstein. According to Klippenstein:Prior to 9/11, there were nine federal agencies that maintained 12 separate watchlists. Watchlists, and the whole watchlisting process, should be as transparent as possible, not the other way around.”“If we don’t explore more why all of these secret lists exist,” the official added, there could be “even more of an environment of paranoia on the ground and more tragic killings.”
