House Minority Leader Nancy Pelosi (D-CA) launched into an extended monologue on the floor of the House of Representatives on Wednesday, using her prerogative as a party leader to mount a filibuster to draw attention to the cause of illegal aliens.
The House, unlike the Senate, does not actually have a filibuster rule that allows members to speak as long as they want. Only the Speaker of the House and the party leaders can hold the floor indefinitely.
