In a discussion with Melissa Melendez, my assemblywoman in Sacramento, she pointed out to me that a Democrat colleague of hers (Reggie Jones-Sawyer of Los Angeles) actually stated that in California, they don't need to adhere to the U.S. Constitution. "We do it anyway."
To the far left Marxist liberal Democrats in Sacramento, the law of the land and the rule of law means nothing to them. All that matters is their agenda.
Congress has the authority to make immigration legislation as per Article I, Section 9 of the United States Constitution. As per Article VI, any law a State makes that is contrary to constitutional laws on the books made by the United States Government are unconstitutional, and therefore, illegal.
