On May 25, 1972, as part of the Dwight D. Eisenhower Memorial Bicentennial Civic Center Act, the Senate passed legislation (S. 3943) legally designating the FBI building as the J. Edgar Hoover Building. A similar bill in the United States House of Representatives (H.R. 16645) was also moving forward. The House bill was amended several times. The House subsequently passed S. 3943 on October 3, after amending it to include the amended language of H.R. 16645. The Senate agreed to the House amendments on October 14. Nixon signed the legislation into law as Public Law 92–520 on October 21, 1972.
