Joint Committee on the Library Members

7 of its 10 members are on the November 3, 2026 ballot — 5 House members (every House seat is up) and 2 Class II senators. Joint committees mix House members, who are all up every two years, with senators, who are only up when their class is on the ballot.

The Joint Committee of Congress on the Library is a joint committee of the Congress. It is chaired by Bryan Steil (R-WI), with Alex Padilla (D-CA) as ranking member. Like every congressional committee, it does the detailed work the full chamber cannot: holding hearings, marking up bills in its jurisdiction before they reach the floor, and overseeing the executive-branch agencies it covers. A bill that never gets a hearing here never gets a vote — which is why the chair's control of the calendar is the committee's most consequential power.

The majority party holds the chair and a majority of seats on every committee, in rough proportion to its margin in the chamber, so the 6–4 split above follows directly from the current party breakdown. Seniority within each party — the rank column — determines who moves up when a seat opens, and the most senior minority member becomes chair if control of the chamber flips.

The committee's official website is cha.house.gov/jointcommittees/joint-committee-library, which carries hearing schedules, bill text and testimony. This roster is rebuilt daily from the official House and Senate membership data, so it reflects vacancies, replacements and reassignments as they are recorded — including the full reshuffle every January when a new Congress organizes.
