Pacheco spearheaded the introduction of high profile landmark federal legislation to force the federal government to release a band of research primates crippled in a federally funded laboratory that had been previously shut down, securing over 200 House Co-Sponsors of the legislation, as well as the signatures of 55 U.S. Senators, ranging from the liberal Senator Ted Kennedy to the conservative Senator Jesse Helms.
This legislation was actively and aggressively opposed and lobbied against by the national biomedical industry, including
- the American Medical Association,
- the Association of American Medical Colleges,
- the U.S. National Institutes of Health,
- the U.S. Department of Agriculture,
- the American Psychological Association,
- . . . and many, many more.
