I watched Pritzker's press conference. You can here. He said no such thing.

He told Trump not to send the National Guard to Chicago; that they are neither needed nor wanted there. And he told citizens that when it does happen to engage in peaceful protest, noting that any guard members that arrive are likely doing so under duress (denying to deploy would risk court martial), and insisting that citizens look to "members of the faith community" for guidance on how to organize.

I don't really agree with that specific choice, but that's what he said.

But also, this:

The state of Illinois is ready to stand against this military deployment with every peaceful tool we have. We will see the Trump administration in court. We will use every lever at our disposal to protect the people of Illinois and their rights. Finally, to the Trump administration officials who are complicit in this scheme. To the public servants who have forsaken their oath to the Constitution to serve the petty whims of an arrogant little man. To any federal official who would come to Chicago and try to incite my people into violence as a pretext for something darker and more dangerous, we are watching and we are taking names. This country has survived darker periods than the one that we're going through right now and eventually the pendulum will swing back, maybe even next year. Donald Trump has already shown himself to have little regard for the many acolytes that he has encouraged to commit crimes on his behalf. You can delay justice for a time, but history shows you cannot prevent it from finding you eventually. If you hurt my people, nothing will stop me, not time or political circumstance, from making sure that you face justice under our constitutional rule of law.

That's more like it.
