Jacob Koppel Javits was an American lawyer and politician. During his time in politics, he represented the state of New York in both houses of the United States Congress. A member of the Republican Party, he also served as the state's Attorney General. Generally considered a liberal Republican, he was often at odds with his own party. A supporter of labor unions, the Great Society, and the civil rights movement, he played a key role in the passing of civil rights legislation. An opponent of the Vietnam War, he drafted the War Powers Resolution in 1973.

The Rockefeller Republicans were members of the United States Republican Party (GOP) in the 1930s–1970s who held moderate-to-liberal views on domestic issues, similar to those of Nelson Rockefeller, Governor of New York (1959–1973) and Vice President of the U.S. (1974–1977). Rockefeller Republicans were most common in the Northeast and the industrial Midwestern states, while they were rare in the South and the West.
