What solution has been proposed for dealing with Sanctuary Cities' refusal to enforce immigration laws?
If the ICE chief wants to bring this all to a head and get the Sanctuary Cities to reverse their course the solution is simple:
Instead of increasing enforcem2 in these jurisdictions-remove ALL ICE agents and inform the public that there will be ZERO enforcement there.  Allow these fools to have their way and drown under the weight of the influx.
