Every trade here is a legally required disclosure, not an allegation — timing can be coincidence. Weigh the pattern against the sources linked on each row.

In plain language
Of 5 disclosed trades, 0 were flagged by the site's published rules.
Too few disclosed trades here to say anything about a pattern. A handful of trades will throw up the odd coincidence for anyone.
Across the whole database, congressional trading beats the market by close to nothing on average, and only slightly more trades look unusual than chance alone would produce. Most members, most of the time, are unremarkable. That is the backdrop for anything you read here. A flag is a prompt to look at the record, never a finding about a person.
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 |
|---|---|---|---|
| Senator, WY | 117th | 2021–2027 | moved to the Senate |
| WY at-large | 111th–114th | 2009–2017 | 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.
