Ken Klippenstein
Investigative journalist specializing in national security, intelligence agencies, and the US surveillance state. Klippenstein spent years at The Nation and The Intercept developing sources inside the intelligence community and government bureaucracy before going fully independent on Substack. He is known for publishing leaked documents and internal government communications that other outlets won't touch, including material on FBI operations and Pentagon activities. His Freedom of Information Act (FOIA) work has produced a steady stream of exclusive stories on the national security apparatus that rarely surface in mainstream coverage.
