A new study by the Center for Responsive Politics and the Sunlight Foundation shows a correlation between outside lobbyist and client giving to campaigns."The investigation identified outside lobbyists that donated to the same members of Congress as their clients, and strongly suggests that special interest giving is enhanced by the K Street contributors they hire."Sen. Max Baucus, D-Mont., chairman of the powerful Senate Finance Committee and author of the main health care reform bill now being debated in the Senate, was one of the biggest beneficiaries of this one-two punch from the lobbyists and their clients. From January 2007 through June 2009, 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."
