The Senate is using a procedural tactic called a "live quorum call," which requires all of the senators to physically go to the floor, to delay their procedural vote on their own version of a stopgap spending bill.

Remember: The Senate has put together its own bipartisan proposal to avert a shutdown — but House Republicans have thrown cold water on that plan, leaving the two chambers at an impasse and the attention on the House GOP.

Key senator comments on House bill: Republican Sen. Rand Paul of Kentucky has vowed all week to slow the voting process beyond the midnight shutdown deadline if a stopgap bill includes funding for the war in Ukraine.

He told CNN on Saturday that he will not slow down the Senate's consideration of the House GOP's 45-day spending bill — which, crucially, does not include Ukraine funding — if it passes the House and the Senate takes it up.

This gives lawmakers a path to consider the spending bill very quickly in the Senate, possibly avoiding a shutdown (or at least shortening it), as long as the bill passes the House and Senate Majority Leader Chuck Schumer brings it to the Senate floor.
