Senate Democrats are rejecting for the 10th time a stopgap spending bill that would reopen the government. They are insisting they won’t back away from demands that Congress take up health care benefits. The repetition of votes on the funding bill has become a daily drumbeat in Congress. It underscores how intractable the situation has become as the vote has at times been the only item on the agenda for the Senate floor. Senate Republicans also held a vote to proceed to a bill to fund the Defense Department and possibly several other areas of government. But Democrats almost all voted against the procedure. The $6.5 billion tapped to ensure the military is paid covers one pay period.
