A gray-haired man in a tan trench coat rang the doorbell at the Electronic Frontier Foundation’s San Francisco offices on January 20, 2006. Mark Klein, retired AT&T technician. Raspy voice. He looked around, then asked Shari Steele, “Do you folks care about privacy?” She invited him in. What followed cracked open the NSA’s mass surveillance apparatus wide enough for the world to glimpse its scale.
Klein had spent years maintaining AT&T’s internet backbone links at the Folsom Street facility. Mid-2003 transfer. There, on the sixth floor, a secret room. Room 641A. No handle on the door. Built in 2002. Accessible only to NSA-cleared personnel. Next to it, a splitter cabinet. Fiber-optic cables from the seventh floor converged. Split. One stream to the internet. The other? Straight to the NSA. Every email. Every web browse. Every bit of U.S. traffic copied wholesale. No warrants. No targets. A “country tap,” as one telecom expert put it to EFF lawyers.
Cindy Cohn, then EFF legal director, recounts the moment in MIT Press Reader. Klein handed over documents. Schematics. Training manuals. Proof the agency sat “on the wire” at the backbone, vacuuming data from millions. EFF attorneys Kevin Bankston and Lee Tien pored over it. Experts confirmed: unequivocal evidence of illegal domestic spying, breaching FISA and the Fourth Amendment. Post-9/11 Patriot Act had blurred lines between foreign NSA work and FBI domestic probes. But this? Mass, untargeted. “Big Brother machine,” Klein called it.
They moved fast. Late January, lawyers for Klein—EFF secured independents to shield him from Espionage Act risks. March 31, 2006: EFF filed in the Hepting class-action against AT&T. Klein’s declaration attached. DOJ got wind. Tony Coppolino called Cohn: “Hi Cindy, it’s Tony Coppolino calling about your Hepting case. I’m baaaack.” He demanded secure delivery. Inspected docs in a SCIF. Warned of hidden classifications. “With all due respect, Cindy, you don’t know if they are classified since they don’t have to have markings.” Government invoked state secrets. Congress later granted telecoms retroactive immunity. Case stalled. But the genie escaped.
Klein’s reveal echoed earlier internal alarms. Thomas Drake, NSA senior executive starting September 11, 2001. Air Force vet. Navy vet. CIA stint. He saw the post-9/11 pivot firsthand. Intelligence “blinking red” pre-attacks. Then, billions poured into Trailblazer—a bloated contractor feast. $1.2 billion flop, canceled 2006. Drake backed ThinThread, William Binney’s efficient tool: encrypted, privacy-protected signals intelligence for foreign threats. Management ignored. Drake went internal: boss, inspector generals, Congress. September 2002 report with Binney, Kirk Wiebe, Ed Loomis, Diane Roark. Waste. Privacy violations. Retaliation followed. 2007 FBI raids. Guns drawn.
Drake’s saga resurfaced in late 2025 podcasts. Jane Turner, FBI whistleblower, interviewed him July 4. Whistleblower of the Week, Part 1. Texas-Vermont roots. SERE training—waterboarding included. Refused fraud on Minstrel program pre-NSA. Part 2 detailed surveillance machine: ThinThread twisted domestic. Espionage Act indictment 2010. Ten felonies. Life possible. Collapsed pre-trial. Misdemeanor plea. Probation. Community service. Snowden cited Drake: no Drake, no Snowden leaks.
November 2025, James O’Keefe grilled Drake. O’Keefe Media. 9/11 failures. Trailblazer coverup. “You’re incentivized to keep the money flowing.” Drake lost pension, house, marriage—FBI ultimatum to wife during raid. Five kids gone. Apple Store job. Yet he persists. March 2026, urged Congress for Daniel Ellsberg Act with vets. Rights & Dissent.
Klein and Drake converged in EFF’s 2012 Jewel suit pushback. Drake, Binney, Wiebe filed declarations. EFF. Room 641A fed the beast they warned against. Klein died March 2025, per EFF tribute. Legacy endures. Backbone taps persisted, evolved—PRISM, XKeyscore via Snowden. But roots trace here. Post-9/11 fear birthed it. Contractors ballooned budgets. Privacy shredded.
Fast-forward. AI amplifies. Drake warned December 2025 with George Zarkadakis: surveillance plus predictive algorithms. Weaponized data. No public debate. Congress rubber-stamps FISA renewals. Immunity lingers. Klein’s splitter? Primitive now. But principle same. Total capture. Indiscriminate.
Whistleblowers pay. Drake: haunted lifelong. Klein risked all. Binney raided, leg lost to diabetes. Yet they spoke. DOJ wields Espionage Act like a club—Drake fourth so charged. Obama era crackdown. Biden no different. Reforms? USA Freedom Act trimmed bulk phone metadata. Barely dented internet side.
So where next? Drake active 2026. Podcasts. Panels. Calls for accountability. Room 641A photo—Klein’s—stares back. Reminder. One technician. One doorbell. Exposed the machine. Boom.
Government fights on. EFF’s Jewel lives, narrowed but pressing. FISA 702 sunsets loom. Debates rage. Drake’s voice: “I betrayed NSA mismanagement.” Not secrets. Truth. And truth costs. Always has.
