Executive orders are orders written by the chief executive, instructing executive branch employees in how they are to carry out their duties. In the case of the Federal government, the chief executive is the President, of course.
I have long been highly critical of how Executive orders have been used. They cannot be used to create laws out of whole cloth, as that is the job of the legislature. What EOs can be used for, however, is to instruct federal employees in how they will carry out the duties that have been assigned to them by law, in my opinion.
So that brings us to our current problem- there are state and local governments that are refusing to abide by or even comply with the enforcement of Federal law. Namely, there are cities who are refusing to comply with ICE in removing illegal immigrants from our country. I would wholeheartedly approve of an EO instructing Federal employees to refuse to issue or approve ANY grants or Federal funding to any local government who declares itself to be a sanctuary city. That would also include providing access to Federal programs like the NCIC or any other crime related database to any police department who refuses to comply with Federal law.
The entire Federal grant system is based upon Presidential Executive Order No. 12372, which was issued by President Reagan in July of 1982. That EO allows states to establish a Single Point of Contact (SPOC) to review proposed federal financial assistance. So Trump could simply modify that EO to make this happen.
The Feds have been tying funding to their edicts for decades. It’s how 21 became the national drinking age nationwide– it’s time that the Trump team begin playing the game.
