Sen. Bernie Sanders (I-VT) lamented centrist Senate Democrats’ decision to join with Republicans in advancing a funding plan to end the government shutdown, casting it as a “very, very bad” vote.

The Senate was able to move a step closer to ending the longest shutdown in U.S. history, passing the funding bill in a test vote on Sunday, with eight Democrats crossing the aisle. While the legislation still needs to overcome more procedural hurdles in the Senate and then pass the House, it ended a deadlock that has led to delays at airports and a lapse in SNAP benefits.
