In 1971, Mike Gravel conducted a one-man filibuster against the Vietnam-era draft and read 4,100 pages of the 7,000-page Pentagon Papers into the Congressional Record.
Notes on verification
Confirmed by multiple independent, reliable sources (NPR, Military Times, The Hill) and detailed background from Wikipedia's Gravel v. United States entry. Minor procedural nuance (subcommittee vs. Senate floor) is well-documented but omitted in most mainstream coverage.
