The U.S. Senate's "long war over the proposed asbestos-litigation trust fund has given the lobbying [3] industry its biggest contracts and busiest revolving door [4], bringing a virtual army of ex-leadership aides back to their former bosses' doorsteps." Fortune 500 companies with "more than $75 million in liability to injured workers" have retained 20 firms to promote the bill, in addition to their in-house lobbyists and the National Association of Manufacturers [5]. The Asbestos Study Group [6], a business coalition, has a $23 million contract with the Democratic lobbying firm Swidler Berlin (and also worked with the now-defunct Republican firm Alexander Strategy Group [7]). Mark Tipps, "former chief of staff and longtime adviser to Senate Majority Leader Bill Frist [8]," is lobbying for the bill at Akin Gump [9]. Lobbying against the bill are Patton Boggs [10], for the Association of Trial Lawyers of America, and Fleishman-Hillard [11], for the Coalition for Asbestos Reform, "a group of smaller businesses."
