Senate Republicans will keep members in Washington through the weekend pending a possible deal with Democrats to end what’s become the longest government shutdown in history.

Senate Majority Leader John Thune (R-SD) will hold another vote Friday to advance a House-passed stopgap funding measure to reopen the government through Nov. 21, according to a source familiar with the matter. The bill has failed to clear a 60-vote filibuster 14 previous times, and Friday’s vote is expected to be no different.
