In the early 1970s, Pepper chaired the Joint House–Senate Committee on Crime; then, in 1977, he became chair of the new House Select Committee on Aging, which became his base as he emerged as the nation's foremost spokesman for the elderly, especially regarding Social Security programs. He succeeded in strengthening Medicare. In 1980 the committee under Pepper's leadership initiated what became a four-year investigation into health care scams that preyed on older people; the report, published in 1984 and commonly called "The Pepper Report", was entitled "Quackery, a $10 Billion Scandal".
