Also PDJT could run a gun running program similar to that of the Obama /Holder gun running program ( Operation Fast and Furious.)
Imagine thousands of armed illegal aliens with plenty of ammunition shooting up the sanctuary cities. Then the Federal Government under PDJT could save the day by simply killing them all off under authority of the Insurrection Act.
Problem solved: Sanctuary Cities destroyed/Tens of thousands of Illegals Dead.
This is exactly the way Obama would weaponize the situation , just as he did along the Southern Border for years, putting weapons into the hands of Drug cartels which killed US Border Agents and many other people.
