Where this comes from

Lobbying Disclosure Act reports (LD-2), LDA.gov. We save our own copy of each page of LDA.gov's list of reports before we read it. These pages were built from our copies on October 16, 2026.

2026-Q2: every page of LDA.gov's list saved and read.

A lobbying report states the registrant's income from the client (a lobbying firm) or its own lobbying expenses (an organization lobbying for itself), for the whole quarter and every issue together. A report of less than $5,000, or of no lobbying activity, states no figure. It is not the amount spent on one bill.

Senate Office of Public Records cannot vouch for the data or analyses derived from these data after the data have been retrieved from LDA.gov.
