When the FBI investigated Kevin White

MuckRock gets copies of FBI documents related to a decade-long federal look into possible corruption during White's term as mayor, most notably revolving around contributions from waste haulers in 1971. White, however, was never formally charged with anything.

The U.S. attorney's office in Boston was "extremely reluctant to conduct (an) open investigation," the report adds, out of fear for "the possibility of harming White's chances in the forthcoming mayorality campaign and a possibility of White's obtaining a slot on the National Democratic ticket as Vice President."
