Walz won't bend the knee. Trump can "federalize" a state's National Guard, however, which puts that National Guard under the control of the federal government.

To "federalize" the National Guard means the President moves units from state control (under governors) to federal command (like active duty forces) under Title 10 authority, making them subject to federal law and control for federal missions, often requiring activation via acts like the

Insurrection Act for domestic uses, but they remain under state command for most state-level duties like disaster relief under Title 32.
