Answer:
Strom Thumond 24-hour speech set the record for the Senate's longest filibuster speech.
Filibuster is the action of preventing the voting a passage of a bill by spending time delivering speeches. A Congress usually has time limits for approving of disapporving bills, and filibuster can be effective in preventing the bill from being voted on time.
Senator Strom Thurmond delivered this speech to keep the Civil Rights Act from being approved, in the end, he lost his bid and president Johnson Sanctioned the act in 1964.
