Baron &amp; Budd, P.C. is one of the largest plaintiffs' law firms in the United States, having won "some of the largest tort lawsuits and settlements on record". Founded in 1977, the firm focuses on individuals, municipalities, and entities harmed by environmental toxins, fraud, or disregard for safety, and a variety of other areas. Their work has included representation of victims of the September 11 attacks and of the "Deepwater Horizon" oil spill. Opponents of mass tort litigation have criticized the firm for the zealousness with which it represents its clients, and for the political activities of some of its attorneys.
