They can write all the laws they want, Supremacy Clause rules. These democrat governors and mayors continue to waste more time and money and confuse their citizens when they say they will resist deportation efforts. They know or should know that federal rules state in matters of national security and fugitive pursuit. Funny how democrats claim to preserve democracy but apparently have never ever read the constitution. Some are lawyers if you can believe that, and if they know the law and ignore it that’s even worse. Ignorance of the law is no excuse. They seem to have a lot of that.
