After winning control of Congress in November 1994, the Republican leadership, working closely with business lobbyists and policy groups, launched an ambitious effort to roll back a century of reform legislationfrom the food and drug laws of the Progressive Era to the New Deal's Social Security Act to the workplace and environmental regulation of the first Nixon administration. Congressional Democrats blocked most of these efforts in the House and Senate, and the Clinton administration vetoed others, but conservatives have continued to press their agendain committee hearings, in mysterious riders attached to appropriations bills, and in the courts, some of which are still dominated by Reagan and Bush administration appointees.
