From the Sunlight Foundation and the Center for Responsive Politics:
From January 2007 through June 2009, Senator Max Baucus collected contributions from 37 outside lobbyists representing PhRMA, the pharmaceutical industry’s chief trade association, and 36 lobbyists who listed drug maker Amgen Inc. as their client. In all, 11 major health and insurance firms had their contributions to Baucus boosted through extra donations from 10 or more of their outside lobbyists.
Make sure to see here the accompanying graphic, which includes companies and trade groups that have hired former Baucus staffers to lobby for them.
