With a batch of House-passed bills languishing in the Senate, a group of far-Left Democrats on Thursday said they’re stepping up pressure on their party colleagues across the Capitol.

Nearly 100 House Democratic lawmakers signed a letter to Senate lawmakers demanding that they begin to take steps to eliminate the filibuster, a rule effectively requiring 60 votes to pass legislation. With the Senate divided 50-50, Democrats generally need at least 10 Republicans to cross the aisle on bills — a tall order amid today’s sharply partisan politics.
