About Mercury Public Affairs

The Los Angeles office of a national bipartisan public-strategy firm. Its registered roster includes former City Council President Herb Wesson, and its client book is dominated by large corporates — energy, telecommunications, media and quick-service restaurants — rather than project-by-project entitlements.

Lobbying fee income

Fees reported to the City of Los Angeles Ethics Commission by this firm’s clients in their quarterly filings. Figures cover City of Los Angeles lobbying only — County, Metro, LAUSD and state work is reported to separate registries and is not included here.
