Senate Majority Leader Mitch McConnell issued a stern rebuke to Democrats pushing to end the legislative filibuster.

A New York Times op-ed by the Kentucky Republican Thursday offers a detailed defense of the filibuster, which effectively requires any piece of legislative to have at least 60 votes in the 100-member chamber, rather than a bare majority of 51. McConnell’s opinion piece comes days after his Democratic predecessor as majority leader, former Sen. Harry Reid of Nevada, called for the filibuster’s demise. Reid argued the practice prevents the will of the people from being carried out and is undemocratic.
