Alexandra... you're behind in events. Gov. after Gov. are now applying "withdrawal of funds"
to cities they  deem to be 'sanctuary cities'.  When the State withholds funds from local agencies, they are out on a limb -- immediately. This is the budget season in many states. We had top down support and bottom up support for assisting immigrants and refugees. NOW, The Fed AND the State level use cutting funding as a weapon, to move the alt/right to the State/local level. State named Sanctuary cities is the new battleground. On to the State elections!
 It happened in Wisconsin and began rolling out as a tactic long ago. Now, there are proposals at the state-level to remove elected officials from office for NOT complying to a State-issued demand to engage in what is  a Federal Function and legal jurisdiction. 
It is do it until someone finds a way to stop you by --????
It will be incumbent on individual Bishops to bear witness, to be disciples of Jesus not just a people who worship him.
