Homeland Security, Who Lobbies on This Issue
Organizations lobbying on homeland security policy issues, as disclosed in Senate LDA filings.
Homeland Security is a high-volume issue area in the federal lobbying record. 16 organizations have collectively reported $414.3M in disclosed lobbying tagged to this issue code, a level typical of long-running policy debates with broad stakeholder participation across multiple sectors.
What These Numbers Mean
Participation on Homeland Security is moderate, with 16 distinct registrants reporting activity. This is the typical breadth for an issue area anchored to one or two specific bills or rulemakings of broad sectoral interest.
The disclosed-spend leader on Homeland Security is Lockheed Martin (grade B) at $69.2M, narrowly ahead of Northrop Grumman at $62.9M. Closely contested issue leaderboards are typical of policy areas where multiple firms with competing interests engage at similar scale.
Issue codes are one of the most useful but least intuitive parts of LDA filings. Registrants must attach at least one general issue area code to each quarterly filing, but the code list is fixed and broad — the same code can cover several distinct policy debates, and filers often use a single code even when working multiple narrower topics within it. The dollar totals on this page are filer-allocated and should be read as a directional signal of where attention is concentrated rather than as audited line items. The original filings are publicly available through the Senate Office of Public Records; the campaign-finance research project at OpenSecrets uses the same filings as one input.

How to Read This Page
The issue page rolls up every LobbySpend-tracked filer that has reported lobbying activity tagged to the Homeland Security general issue code at any point in the years tracked. The total-spend number sums filer-allocated dollars across those filings, deduplicated against amendments. The organization count reflects unique registrants, not unique filings — a registrant that filed every quarter for five years is still counted once.
Cross-cutting issues (Taxation, Health Issues, Defense) tend to attract a long tail of mid-tier filers from many sectors at once. Narrow issues (Postal, Tobacco, Religion) concentrate participation in a small set of anchor stakeholders. Both patterns are normal in LDA data — the structure of the issue-code list is what produces the difference, not any underlying judgment about the relative importance of the policy area. For the full methodology, including how the Influence Score weights total spend, issue breadth, and revolving-door staffing, see the methodology page.
