A federal judge blocked Trump's executive order threatening to withhold federal grants from so-called "sanctuary cities" because it was overly vague and broad.
Attorney General Jeff Sessions has issued a memo narrowly redefining the Trump regime's position to the point that Trump's original order is effectively meaningless.
“Sanctuary city” is a broad term, but is most often applied to jurisdictions that don’t comply with all of Immigration and Customs Enforcement’s “detainer” requests to hold individuals who would otherwise be released. Yet instead of going after any city or county that doesn’t comply with ICE’s requests, the executive order will target jurisdictions that specifically don’t comply with a law to share information with the federal government for immigration purposes.
There are no jurisdictions, at least not to my knowledge, that refuse to share information with the federal government. This is now an executive order that may not apply to anyone at all.
You may recall that police departments across the country became enraged last month because they were being included on the Trump regime's list of naughty cities even though they were fully complying with the law.
