One of the most damaging arguments by the bill's opponents was that once passed, the bill would require forced busing to achieve certain racial quotas in schools. Proponents of the bill, such as Emanuel Celler and Jacob Javits, said that the bill would not authorize such measures. Leading sponsor Senator Hubert Humphrey (D-MN) wrote two amendments specifically designed to outlaw busing. Humphrey said "if the bill were to compel it, it would be a violation the Constitution, because it would be handling the matter on the basis of race and we would be transporting children because of race." While Javits said any government official who sought to use the bill for busing purposes "would be making a fool of himself," two years later the Department of Health, Education and Welfare said that Southern school districts would be required to meet mathematical ratios of students by busing.
