Former legislative director for the Senate Subcommittee on Air and Water Pollution, and the sole named eyewitness behind the vault's flagged claim that Senator Eagleton championed the Clean Air Act's citizen-suit provision to guard against regulatory capture. That claim rests entirely on a June 2008 telephone interview Billings gave to Frank Manheim, decades after the events and with no public transcript — a single-witness, no-contemporaneous-record chain that keeps the downstream claim at `seedling` regardless of how plausible the story is.
