Every Matter Under Review the Federal Election Commission has docketed since 1975 — 7,670 cases covering illegal corporate / foreign / in-the-name-of-another contributions, coordination violations, conduit-contribution schemes, and disclosure failures. Each MUR includes the respondents, subjects (statutes/regs cited), open + close dates, dispositions per respondent (Conciliation / Dismissed / No Reason to Believe), and penalty amounts. Pairs with `lobbying_filing` for the full money-in-politics picture.
