Financial disclosures and stock trades
Ken Buck’s financial disclosure reports and STOCK Act trade reports are published by Congress.

Power & Politics does not copy or republish these reports.
Court cases naming this member in their official role
Federal cases whose public caption explicitly names this person as a United States senator or representative in an official capacity, during a term recorded in this file. The date on each line is the date of that record, not necessarily the day the case was filed. Being named in an official-capacity case is not a finding about the person, and nothing here says who won. Personal matters are left out entirely.
We have not found a public court record that clearly names this person in their official role, matches the dates they held office, and comes from a court we can follow. That does not mean no case exists. It means we have no qualifying record to show here.
Case records come from each court's own docket and from the United States Courts Opinions collection published by the Government Publishing Office. Select any case to open the official record. Search another politician or see sources and methodology.
