And “DACA” negated.
And Sanctuary cities defunded.
And highway funds denied to states that issue drivers license to illegals.
And Medicare matching funds denied to states that service illegals.
And Student Loan funds denied to institutions that allow illegals.
And Law Enforcement funds denied to states that do not cooperate with immigration law.
I could go on...
