On August 29, 1957, Senator Strom Thurmond of South Carolina set the filibuster record in the U.S. Senate. Sen Thurmond filibustered against the Civil Rights Act of 1967. In a filibuster, a senator may continue to speak indefinitely to prevent a final vote on the bill. Some read the phone book, cite recipes or read the Declaration of Independence.
