If Trump sends the National Guard into cities without the consent of governors, state leaders would be able to file court challenges, as California Governor Gavin Newsom did to block Trump from federalizing the National Guard to quell protests and riots over his immigration policy in Los Angeles earlier this summer, Banks said.

President Donald Trump says he plans to deploy National Guard troops to cities like Chicago, New York, and Baltimore, raising questions about his legal authority to do so.

Gov. JB Pritzker vowed Monday to stop President Donald Trump from deploying the National Guard to Chicago, dismissing Trump’s latest pledge to combat crime as cover for an unconstitutional federal overreach.
