What is happening in the Senate over the weekend? So what is really happening in the Senate? The House did pass the spending bill. But the Senate minority, led by Chuck Schumer, is leading a filibuster and refusing to vote for cloture. The cloture rule–Rule 22–is the only formal procedure that Senate rules provide for breaking a filibuster. A filibuster is an attempt to block or delay Senate action on a bill or other matter. Under cloture, the Senate may limit consideration of a pending matter to 30 additional hours of debate. Those who voted no on cloture have delayed the vote on the actual bill. Needing 60 votes to invoke cloture, Majority Leader Mitch McConnell only got 51. Five Democrats (Joe Donnelly, Heidi Heitkamp, Doug Jones, Joe Manchin and Claire McCaskill), all from states carried by Donald Trump in 2016, voted with the Republicans to keep the government open on the GOP’s terms. Four Republicans (Jeff Flake, Lindsay Graham, Mike Lee and Rand Paul) voted against the continuing resolution for varying reasons, and John McCain was absent.
