Newest first. Nothing here is ranked, featured or promoted, and an article appears because it names this member, not because of what it says about them.

Headlines are reproduced as published by the outlet named beside them and link to the original. The Vote Files does not write, edit or endorse them. Outlet positions are our own and describe an outlet's editorial orientation, not the accuracy of its reporting. Our method is on the sources page.

Looked up

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.

Financial disclosures and stock trades

Chuck Grassley’s financial disclosure reports and STOCK Act trade reports are published by Congress. Search them yourself on the official sites: House financial disclosures (Clerk of the House) ↗ and Senate financial disclosures (Secretary of the Senate) ↗. VoteFiles does not copy or republish these reports.

In the courts

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.

Campaign money

Official totals reported to the FEC

Registered with the FEC as a candidate for the U.S. Senate for the 2028 election (FEC candidate ID S0IA00028). FEC registration does not mean a candidate is on the ballot.

2025–2026 cycle, through June 30, 2026: total receipts $328,050.45, total disbursements $300,738.25, cash on hand $360,213.14. FEC totals published October 12, 2026.

Federal campaign records before 1980 are not shown. No official digitized record exists.

From the Federal Election Commission's public data. We matched this member to the FEC record by office, state, district and last name, and we show nothing when the match is not exact.
