The U.S. government faces an impending shutdown after Senate Republicans failed to secure passage of a continuing resolution aimed at keeping federal operations open. The Republican plan, which would have avoided a shutdown through November 21, collapsed in the Senate following opposition from Democratic lawmakers.

Democrats opposed the measure, citing concerns over healthcare access for undocumented immigrants. The standoff has triggered a government closure set to begin at midnight, marking the first such event since 2019. Essential services, including mail delivery and Social Security payments, will remain operational, while non-essential agencies face reduced staffing and potential closures.

Senate Democrats blocked the funding bill with a 55-45 vote, despite support from two Democratic senators, John Fetterman of Pennsylvania and Catherine Cortez Masto of Nevada, who joined Republicans in backing the measure. Independent Senator Angus King of Maine also supported the plan. Conversely, Republican Senator Rand Paul of Kentucky opposed the bill, aligning with Democrats in its defeat.

The White House has instructed federal agencies to prepare for a shutdown, with President Trump signaling potential benefits from the crisis. Earlier this week, he suggested that government closures could lead to “getting rid of a lot of things we don’t want.” A second vote on the Republican funding plan is scheduled for Wednesday.
