Campaign money 2026 cycle
Campaign finance from the FEC, shown as context beside the trading record. We do not draw a line from any donor to any trade: the FEC's donor data cannot support that honestly, and inventing the link would be the kind of unsourced inference this site refuses. Read the two together and judge for yourself.
Seat & district history
| Seat | Congresses | Served | Change |
|---|---|---|---|
| CA-4 | 118th–119th | 2023–2027 | district renumbered from 5 |
| CA-5 | 113th–117th | 2013–2023 | district renumbered from 1 |
| CA-1 | 106th–112th | 1999–2013 | first seat |
District numbers change when a state is redistricted, so a renumbering here is not necessarily a move — the boundaries were redrawn around the member. Term records come from the public congress-legislators dataset.

The published roster covers only the sitting Congress, so earlier assignments are reconstructed from the dated version history of that same public dataset, sampled monthly back to 2012. Observed is the span across which we actually saw the seat held — it is evidence of tenure, not a precise start and end date, and a seat that changed hands between two monthly samples may be dated up to a month out. Committees with no history recorded are absent because no snapshot showed them, which is not evidence the member held no seat.
