The Hitchhiker's Guide to Congress' options on hamstringing Trump's war powers in Iran

There is tension in the Constitution as to which branch of government wields "war powers."

Article I, Section 8 of the Constitution gives Congress the power "To declare War," (right between the parts where Congress may "punish Piracies" and "grant Letters of Marque and Reprisal). But Article II, Section 2 says the president is "Commander in Chief."

The founders wanted to make power diffuse. That’s why certain constitutional authorities are spread out in the Constitution.
