U.S. Senator from Maine who chaired the Senate Subcommittee on Air and Water Pollution and is widely credited as the principal author of the Clean Air Act of 1970; later the Democratic vice-presidential nominee in 1968 and U.S. Secretary of State. Matters to this vault as the figure who read the Senate Public Works Committee's citizen-suit rationale into the floor record on September 21, 1970 — the legislative-history primary source establishing that §304's own stated justification is agency distrust ("government initiative... has been restrained"), not a civil-rights-litigation analogy, a silence that bears on the vault's standing question about the citizen suit's origins alongside [[entity-leon-billings|Leon Billings]]'s account of Senator Eagleton's motives.
