On Dec 3, the House introduced H.J. Res 143 extending continuing appropriations for certain departments and agencies until Dec 21, 2018. Cruz's bill can be offered as an amendment to H.J. Res 143 and be voted on by the Senate. If passed, it would go back to the House.
The next chance to get it through this session will be when Congress has to extend or replace the continuing appropriation before Dec 21.
