Organizations that paid for trips taken by House members and their staff in connection with official duties, from the post-travel filings the Clerk of the House publishes for six years. Senate filings name the sponsor only inside a scanned document, so they appear on each senator's profile but not here. A trip is one traveler's filing; amendments of it count once.
683 sponsors, most trips first. Filings last checked Oct 24, 2026.
