Cora Currier and her colleagues at The Intercept publicly released the FBI's confidential rulebooks.
Notes on verification
Confirmed by The Intercept's own published series, Wikipedia's entry on Terry J. Albury, and independent corroboration from Columbia Journalism Review. Multiple reporters were involved, consistent with 'her colleagues' phrasing.
