Trump should defund state block grants but make up the difference through supplemental funding that goes directly to non sanctuary cities.
If the Democrats fight this then just defund the entire state and let the Democrats deal with it.
To do this requires a president with the courage to defy the media and the political elites.
Why waste all the time and effort?? This is a Law Enforcement problem, Start ARRESTING and PROSECUTING Public Officials, beginning with Eric Garcetti and LAPD Chief Charlie Beck.
Then immediately begin going through VOTER Registration rolls to look for NON-CITIZENS that Illegally Voted. IMMEDIATELY DEPORT ALL OF THEM. If any of them can be demonstrated to have Collected Taxpayer Funds, ARREST AND CHARGE the Head of that Agency and ALL of it’s Employee’s that have ILLEGALLY GIVEN TAXPAYER MONEY to Foreign Criminal Invaders.
THIS WILL GET THEIR ATTENTION much faster and Produce tangible results immediately.
