This Executive Order relies on the unsupported assertion that immigration constitutes an "invasion" to claim claim the authority for DOJ and DHS to identify and punish so-called "sanctuary" jurisdictions. There is no legal definition of a "sanctuary" or "welcoming" city or state; it usually refers to jurisdictions that decline to use their own local law enforcement resources to carry out federal immigration enforcement, which states and localities have the right to do. However, this EO defines "sanctuary" jurisdictions as those that "obstruct the enforcement of Federal immigration laws," and incorrectly claims that this constitutes a "lawless insurrection" against the federal government. The EO instructs DOJ to maintain the list of sanctuary jurisdictions, and inform all jurisdictions on the list of their designations. It unlawfully instructs executive branch agencies to strip designated jurisdictions of federal funding, and potentially to target them for prosecution under federal harboring, obstruction, conspiracy, and RICO statutes. It also encourages other undefined "measures" and "action" by DOJ and DHS. Finally, DHS is instructed to develop rules to prevent ineligible noncitizens from receiving public benefits through private organizations like nonprofits, and DOJ is instructed to sue states that provide in-state tuition at state colleges and universities to state residents who lack U.S. citizenship.
