AZ HB2320

Prohibits the Arizona National Guard from being called into active duty combat unless the United States Congress passes an official declaration of war or takes official action under Article I, Section 8, Clause 15 of the U.S. Constitution to execute federal laws, repel invasion, or suppress insurrection.

Defines "active duty combat" as participating in armed conflict, performing hazardous service in a foreign state, or performing duty through an instrumentality of war during active federal military service.

Requires the governor to take all necessary actions to comply with these restrictions on National Guard deployment.

Establishes legislative findings asserting that Congress has exclusive constitutional power over war declarations and that the executive branch has unconstitutionally assumed this power over the past 70 years.

Cites founding fathers including George Washington, James Madison, Thomas Jefferson, and Alexander Hamilton to support the principle that only Congress can authorize war.
