Beginning in 1971, he served on the House Appropriations Committee for more than two decades and authored a number of bills, many of which were not universally popular, which offered support for groups he saw as disenfranchised; many of his actions were on behalf of veterans, the elderly, and Mexican-Americans. In 1967 he wrote the first bill giving federal support to bilingual education, creating specialized language instruction for immigrant populations. As Chairman of the House Select Committee on Aging, he led a successful campaign to restore $15 million in funding the low-cost health programs for senior citizens and an expanded public housing program for seniors. In 1982 he worked to preserve the Meals on Wheels program and veterans' preferences in hiring. In the early 1980s, against the wishes of many of his own constituents, he argued for expanded funding for AIDS research.
