Lawmakers say a government shutdown appears inevitable as the deadline of midnight Sunday approaches. Senate conservatives want to delay a vote on a stopgap funding bill to give the House leverage to negotiate spending cuts. It’s unclear if the House will pass its own funding measure or accept the Senate’s bill. Senators expect votes through the weekend to pass a funding bill to the House. Rand Paul says he will object to expedite a vote without Ukraine aid. A shutdown now seems likely and federal workers could go without pay for a week or two. Negotiations between the House and Senate could last days or weeks if they need to compromise on a stopgap bill.

The document highlights Rand Paul’s threat to slow down passage of the funding stopgap unless Ukraine aid is removed, indicating one senator’s objection may be enough to cause at least a brief government shutdown.
