3 of the lobbyists named on those filings share a name with someone in the congressional record — a former member, or a name in the House staff directory. This is a name match, not a verified identity: we hold today’s House roster and no employment history at all, and the Senate publishes no staff directory, so the names are shown rather than only counted.
