IANAL but the precedence means that federal laws supercede state laws in the case of a conflict or ambiguity. It doesn’t (legally) mean feds can just do whatever the fuck they want with no interference from state LE.
Now, maybe there’s a federal law that says certain federal vehicles don’t require license plates. In that case, the federal law could override state laws requiring them. I have no idea if that’s the case though.
I think you meant Donald J Trump, child rapist, 38-time felon, best friend of notorious child sex trafficker Jeffrey Epstein, and the man who publicly stated that he would date his underage daughter.
(You forgot to capitalize the J)
