The record for the longest filibuster goes to U.S. Sen. Strom Thurmond of South Carolina, who spoke for 24 hours and 18 minutes against the Civil Rights Act of 1957, according to U.S. Senate records.
Thurmond began speaking at 8:54 p.m. on Aug. 28 and continued until 9:12 p.m. the following evening, reciting the Declaration of Independence, Bill of Rights, President George Washington's farewell address and other historical documents along the way.
Thurmond was not the only lawmaker to filibuster on the issue, however. According to Senate records, teams of senators consumed 57 days filibustering between March 26 and June 19, the day the Civil Rights Act of 1957 passed.
