Independent expenditures are reported to the FEC by the spending committee, not the member's campaign. A committee is marked single-candidate when 80% or more of its cycle independent-expenditure dollars concern one candidate. Donors are named only at $50,000 or more to a super PAC or joint fundraising committee. For leadership PACs, individuals are named at $50,000 or more; organizations and PACs at $5,000 or more. The 2026 cycle is still in progress.
Amounts are each donor's net total of itemized contributions across the cycle (primary, general, and runoff elections combined), after subtracting refunds, not single gifts. Receipts marked as received in error, returned, or refunded are excluded, and refunds to the donor are subtracted. Joint-fundraising shares are included: the member committee's itemized share of joint-fundraising proceeds (FEC transaction type 15J) counts toward the donor's total, while the joint fundraising committee's own transfers are not counted separately. Donors are named only when their net cycle total is $1,000 or more; smaller donors appear only in the aggregate count and total below each table. Where a returned receipt of $10,000 or more affects a total, it is noted below the table. Lists cover itemized individual gifts to the member's principal campaign committee only. Employer and occupation are self-reported. The 2026 cycle is still in progress.
Donor figures are net of refunds from the FEC individual-contribution bulk files (2024 and 2026 cycles, each itemization taken at its latest amended version before any exclusion), rebuilt and reconciled row by row against the previous release on 2026-10-02; see methodology for the method and the reconciliation counts.
