consultant to United States Senator Abe Ribicoff, reported to the senator that he suspected he was being followed. Ribicoff convened an inquiry that called GM CEO James Roche who admitted, when placed under oath, that the company had hired a private detective agency to investigate Nader. Nader sued GM for invasion of privacy, settling the case for $425,000 and using the proceeds to found the activist organization known as the Center for the Study of Responsive Law. A year following the publication of Unsafe at Any Speed, Congress unanimously enacted the National Traffic and Motor Vehicle Safety Act. Speaker of the United States House of Representatives John William McCormack said the passage of the National Traffic and Motor Vehicle Safety Act was due to the "crusading spirit of one individual who believed he could do something: Ralph Nader".
