From the Document: "The possible use of federal armed forces as part of the U.S. executive branch's response to incidents of violence during racial justice protests has raised questions about how the military is controlled by domestic political institutions and the U.S. military's relationship with American society. Article I of the U.S. Constitution grants specific powers to Congress, making the legislative branch a key actor in governing, overseeing, and funding the U.S. military."
