Not getting as much notice today was that the Court refused to hear Trump’s challenge to California’s Sanctuary law, under which the State refuses to cooperate with Federal immigration enforcement activities. This is another example of the hypocrisy of conservatives, as the right of states to refuse to have their police agencies commandeered into enforcing federal law has been well respected ever since the Tenth Amendment was passed in the 1790s. But Trump doesn’t care about the Constitution. In this case the Court refused to be Judicial Activists even though the Trump Administration wanted it to be.
Interestingly, there is nothing in the Constitution that explicitly gives the federal government the power to restrict immigration, only to regulate naturalization. The Founding Fathers would never have imagined the racist national origins quota system, but the courts upheld it anyway.
