The Center for Public Integrity publishes this month a documented report on the record investments in the pharmaceutical industry in the United States in terms of institutional lobbying, reaching 189.1 million dollars in 2007. Pfizer, Sanofi-Aventis, Merck & Co ... becomes as such the largest lobby in Washington. Drawing a parallel with the very recent European registry of lobbyists designed to ensure greater transparency in EU, it is thanks to Lobbying Disclosure Act dating from 1995 that the Center for Public Integrity has had access to data made ??available by the U.S. Senate.
