The growing, productive women's movements of the 1960s and 1970s renewed support for the amendment. U.S. Representative Martha Griffiths of Michigan reintroduced it in 1971, leading to its approval by the House of Representatives that year. After it passed in the Senate on March 22, 1972, it went to state legislatures for ratification. Congress originally set a deadline of March 22, 1979, by which point at least 38 states needed to ratify the amendment. It reached 35 by 1977, with broad bipartisan support including both major political parties and Presidents Nixon, Ford, and Carter. However, when Phyllis Schlafly mobilized conservative women in opposition, four states rescinded their ratification, although whether a state may do so is disputed. The amendment did not reach the necessary 38 states by the deadline. President Carter signed a controversial extension of the deadline to 1982, but that time saw no additional ratifications.
