Wikipedia lookups, last 30 days
How often people went and read about this member. It counts lookups and nothing else: not approval, not support, and not how important a member is.
Daily counts from the Wikimedia pageviews API, automated traffic excluded. Wikipedia counts a redirect separately from the article it points to, so these are a floor rather than a total. Our method is on the sources page.
Verified official-capacity cases
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-capacity matters are excluded entirely.
No case has passed the official-capacity identity, subject-matter, and court-follow-through gates for this file. That is not a statement that no case exists. It means VoteFiles has no qualifying public record to display 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.
