These Clerk index records match this FEC record by first name, last name, state, and House district. The sources do not share a durable person identifier, so Election.org labels the join instead of asserting identity. These are personal disclosure filings—not campaign receipts or spending.
A filing or securities transaction is not evidence of wrongdoing, material nonpublic information, intent, profit, loss, or a conflict of interest. The join remains only an exact first-name, last-name, state, and House-district match.

Source: FEC contributions-from-committees-to-candidates and independent-expenditure bulk files, checked Oct 29, 2026. Committee transactions retain only the latest filing version for stable transaction IDs. Independent-expenditure rows from superseded filings are removed through the FEC previous-filing chain. Memo entries remain included because the FEC bulk-file documentation instructs analysts to include them.
These panels show privacy-thresholded itemized individual-receipt activity and amendment-normalized operating expenditures. They are descriptive slices of filings—not a complete substitute for the official financial summary.
Monthly transaction activity from the FEC individual-contributions file. Current-cycle files can contain earlier-dated transactions; signed amendments, refunds, reattributions, and memo entries remain in the source-defined analysis.
Only committee/month cells with at least 5 distinct reported contributors are published. A missing cell can reflect source absence or the privacy threshold; it does not mean zero activity. Published amounts are unchanged.

State is taken from the contributor address on the FEC row. It does not prove residence, citizenship, employer location, or the ultimate economic source of funds.
Only committee/state groups with at least 5 distinct reported contributors are published. Percentages divide by the sum of all positive published, privacy-thresholded committee/state cells, including cells beyond the top 12 shown. Zero and negative state cells are excluded from this denominator; these shares do not describe all contributions or all campaign receipts.

FEC filer-selected categories from Schedule B operating expenditures. Memo-code X rows are excluded because the FEC says they are not included in the itemization total.
Organization payees only. Election.org excludes individual payees and conservatively normalizes names; similar names are not asserted to be one legal entity.

These totals combine itemized contributions from individuals who reported the same employer. They do not show that the employer directed, funded, or endorsed any contribution.
Only employer/recipient groups with at least 5 distinct reported contributors are published, with at most 50 groups per recipient committee. Individual names and addresses are not included. Totals are net current-file amounts after amendment normalization and may include refunds, reattributions, or memo entries.
