Money & lobbying ties
Political committees that gave to this member’s principal campaign committee.
45 committees, $106,000 total (cycle 2024). Source: FEC Schedule A, line 11C. A contribution is a documented financial relationship — it is not evidence that any vote was influenced by it. Conduit committees such as ActBlue and WinRed appear here as the FEC records them, but they forward earmarked donations from individuals rather than giving money of their own.

Industry rollups are not shown
This would be powered by OpenSecrets, which this project does not use. It moved behind a paid subscription, and no free source codes contributors by industry. Rather than guess an industry from a committee name, the filings are shown exactly as the FEC records them. It would otherwise show these committees grouped into industries and sectors.
