How long have they been in office, and where?

Every federal term on record, with party changes, chamber changes, and breaks in service marked.

Did voters choose them for every term?

Whether each term began with a general election, a special election, or an appointment by a governor.

No appointment or special election is recorded for this member. The roster marks how a term began for fewer than one term in a hundred, so an absence here means the record is silent — not that every term began with a general election.

An appointed senator holds the seat lawfully and with full powers; the point is only that no ballot was cast for them at the time. A special election is the opposite case — voters did choose, just outside the normal cycle. House vacancies can only be filled by election, never by appointment, which is why appointments appear on Senate pages alone.

What power do they hold inside the chamber?

Formal leadership posts — Speaker, Whip, Conference Chair, President Pro Tempore — with the years each was held.

This member has not held a formal leadership post.

Leadership is distinct from committee work. It controls what reaches the floor and when, which is power that never appears in a voting record.

Has their family served in Congress before?

Relatives who have also held federal office.

No relatives of this member are recorded as having served in Congress.

A political family is not a finding about anyone's conduct. It is shown because it is on the public record and is otherwise invisible.

Who held this seat before them?

Every person who has ever occupied this seat, and the party of each.

Senate seats are tracked by class, which never changes, so that lineage is continuous. House districts are tracked by number, and redistricting reassigns numbers — the 3rd district of 1850 is not the same territory as the 3rd district today. Read the older entries as the history of the number, not of the ground.

How did they vote on the bills that came to a vote?

Every recorded vote of their career. Most bills never reach a recorded vote at all, so this is not the whole of what Congress considered.

674 recorded votes. The strip runs oldest to newest, left to right; the table below is most recent first.

On final passage

Most roll calls are procedural, not final passage. A vote against a motion to recommit is not a vote against the bill. Final passage is shown by default; procedural votes are behind the toggle.

What passed without anyone going on the record?

Bills their chamber approved by voice vote or unanimous consent, where no individual position was ever recorded.

None detected. This section currently recognises a voice-vote passage only when it is a bill's most recent action, which misses most House passages — the Senate usually acts last. Treat an empty result here as incomplete, not as a finding that nothing passed this way.

A large share of legislation passes this way. Absence from this member's vote list does not mean absence from the chamber's work.

Did they vote to weaken bills they then voted for?

Amendment votes paired with the final passage vote on the same bill.

Both votes are shown side by side with no characterisation. Amending a bill is ordinary legislating; the pairing is shown because it is otherwise invisible, not because it is an accusation.

How have they voted on the issues you care about?

Their final-passage votes grouped by policy area, with the outcome of each bill.

How this is calculated Counts of Yea, Nay, and Not Voting on final-passage votes, grouped by the bill's CRS policy area. Nothing is weighted and no direction is scored — these are counts.

A vote on a bill is not a position on an issue. Members vote against bills they support over cost, over an unrelated provision, or over process. Read the individual votes rather than the totals.

Source · Policy areas assigned by the Congressional Research Service and published through the Congress.gov API. This site uses the CRS classification and does not create its own.

How does this compare with the rest of their delegation?

The same final-passage votes, alongside how the other members from their state voted.

Agreement or disagreement with colleagues is not a measure of anything. It is shown because it is the comparison a constituent is usually trying to make and cannot easily make anywhere else.

What did they write, and what happened to it?

Bills sponsored and cosponsored, and how far each one got — enacted, passed one chamber, or died in committee.

Did they try to force votes leadership would not schedule?

Discharge petition signatures — the mechanism for pulling a bill out of committee against the leadership's wishes.

What do they have power over?

Committee and subcommittee assignments, with chair and ranking-member roles.

A committee name says little about what it controls. The jurisdiction is the committee's own description of its remit, and it is what makes the holdings section below meaningful.

Who funds their campaign?

Money raised and spent by their principal campaign committee in the current two-year period, 2025–26, and where it came from.

Total raised

$2,108,920

Total spent

$1,518,045

Cash on hand

$1,285,018

From individuals

$1,336,291

From committees

$724,150

Every member is shown over the same two-year window. A senator's election cycle runs six years, so a senator's lifetime campaign totals are larger than this; showing two years for everyone keeps the figures comparable across the House and Senate. Contributor employer is self-reported by the donor. It groups individuals who share an employer. It is not a contribution from that company — corporations cannot give to candidates.

Who are the people writing the largest checks?

Every individual the FEC itemises, by name, with the employer and occupation they reported.

Itemised donors

$716,690

Largest single donor

$10,500

205 itemised donors are on file and all are listed above. The complete list, with no cut-off, is in this CSV. Contributions under $200 in total are not itemised by law, so no public record names those donors — for most campaigns that is a substantial share of the money raised. Street addresses appear in the FEC filing and are deliberately not reproduced here.

How this is calculated Contributions summed per person across the cycle. The FEC itemises a donor once their total passes $200; below that, no public record names them.

Employer and occupation are self-reported by the donor and are often blank or vague. Street addresses appear in the FEC filing and are deliberately not reproduced here — city and state answer whether money is local without putting anyone's home on a searchable page.

Who spends on their behalf without asking them?

Independent expenditures supporting or opposing this member, by outside groups.

This money is legally beyond the candidate's control and cannot be coordinated with the campaign. It is shown separately from campaign finance for that reason. Spending against a member is listed alongside spending for them.

Source · FEC Schedule E, independent expenditures

Do they run a second committee most people never see?

Leadership PACs are separate from the campaign. They may pay for travel, meals, and contributions to other members.

A leadership PAC is legal and common. It is shown because almost no voter knows these exist, not because having one is irregular.

Source · FEC candidate committees, filtered to leadership PACs

Which colleagues do they fund?

Contributions from this member's committees to other members' campaigns — the internal influence economy of Congress.

Recipients are matched on surname against the sitting roster. A common surname can produce a false match, so this is shown as a name match and linked to the primary filing rather than asserted as a transfer.

Who else does their campaign pay?

Where campaign money goes — consultants, vendors, salaries, and any payments to the member's relatives or own businesses.

Payments to relatives are disclosed and are not by themselves improper. They are flagged only where the payee surname matches the member's, and that match is shown as a match, not as a finding.

Source · FEC Schedule B, itemized disbursements

Did they lend their campaign money and get paid back?

Candidate loans to the campaign, and repayments of those loans out of money raised afterward.

Source · FEC Schedule C loans and Schedule B repayments

Who lobbies them, and who pays for their events?

Contributions and honorary payments disclosed by registered lobbyists, plus lobbying filings naming their committees.

327 disclosures in all; the largest 40 are listed.

What do they own, and what have they traded?

Assets, liabilities, outside income, and individual securities transactions — disclosed because they hold federal office.

Amounts are reported as ranges, not exact figures — that is how the form works. Holdings owned by a dependent child are excluded from this site entirely.

Source · Office of the Clerk, U.S. House. Ethics in Government Act and STOCK Act filings.

Did they disclose their trades on time?

The STOCK Act requires a transaction to be reported within 45 days. This is the gap between each trade and its filing.

Not in the local cache yet. python3 fd_ingest.py --years 2025 2026 --parse-ptr

How this is calculated Filing date minus transaction date, in days. Statutory deadline is 45. Each trade shown individually; no average, because one 300-day filing and nine on-time ones is not the same as ten 30-day filings.

A late filing is a fact against a statutory deadline. The Ethics Committees, not this site, determine whether a late filing is a violation.

Source · Computed from filing dates in House Clerk PTR documents

Do their holdings overlap what their committees decide?

Committee jurisdiction on one side, disclosed holdings and contributor industries on the other.

These two lists are placed side by side and nothing is asserted about the relationship between them. An overlap is not evidence of wrongdoing. The reader draws the conclusion; this site does not.
