Leave it shut down until the Wall is actually built.
I would love for Trump to get everything together in a nice neat bundle, then go to the American people again from the oval office and say.
1. Hes declaring an Emergency on our southern border and has instructed the Army to build the wall.
2. Money for the wall, all $25 billion will come from the unused money that was returned to the govt (by the armed forces).
3. He will sign the current bill that calls for an additional $1.5 billion for the wall.
4. He will reopen the govt.
