To cut federal funding of Sanctuary Cities and use those funds for building a wall on the border with Mexico, and for other purposes.

Make Sanctuary Cities Pay for the Wall Act of 2018 This bill directs the Department of Homeland Security (DHS) to establish a DHS account for the planning, design, and construction of a U.S.-Mexico border barrier. Certain housing, community development, and public works appropriations for sanctuary cities, localities, or states shall be withheld and deposited into such account. DHS: (1) may decline to transfer an alien in its custody to a sanctuary jurisdiction regardless of whether such jurisdiction has issued a writ or warrant, (2) shall not transfer an alien under a final order of removal (or a restatement of an order of removal) to a sanctuary jurisdiction, and (3) shall determine and report to Congress each year which political subdivisions or states are sanctuary jurisdictions.
