ROLL CALL: Rand Paul Threatens to Keep Senate in Session for Vote on Pakistan Aid. “Paul says he will filibuster any effort to expedite Senate business until he secures the votes. That could delay the Senate’s departure until the coming weekend because it is not scheduled to hold a cloture vote on taking up the six-month stopgap spending package until Wednesday. If Reid and Paul remain at loggerheads, the timeline for finishing the CR could be pushed as late as Sunday. The measure itself is not in jeopardy; it got through the House easily last week, 329-91.”
