In 1957, during the Dwight D. Eisenhower administration, Rumsfeld served as administrative assistant to David S. Dennison Jr., a Congressman representing the 11th district of Ohio.
In 1959, he moved on to become a staff assistant to Congressman Robert P. Griffin of Michigan.
Engaging in a two-year stint with an investment banking firm, A. G. Becker & Co., from 1960 to 1962, Rumsfeld would instead set his sights on becoming a member of Congress.

He was elected to the United States House of Representatives for Illinois's 13th congressional district in 1962, at the age of 30, and was re-elected by large majorities in 1964, 1966, and 1968.
While in Congress, he served on the Joint Economic Committee, the Committee on Science and Aeronautics, and the Government Operations Committee, as well as on the Subcommittees on Military and Foreign Operations.
He was also a co-founder of the Japanese-American Inter-Parliamentary Council in addition to being a leading cosponsor of the Freedom of Information Act.

As a young Congressman, Rumsfeld attended seminars at the University of Chicago, an experience he credits with introducing him to the idea of an all volunteer military, and to the economist Milton Friedman and the Chicago School of Economics.
He would later take part in Friedman's PBS series Free to Choose.

During his tenure in the House, Rumsfeld voted in favor of Civil Rights Acts of 1964 and 1968, and the Voting Rights Act of 1965.
