Stephen Miller ran military strikes that killed at least 17 people. The deputy chief of staff bypassed the secretary of state to order lethal attacks on Venezuelan boats. His justification? Article II authority—presidential war powers meant for defending America from attack. But Venezuela didn't attack us. Miller claims a gang designation is enough to invoke war powers and kill people in international waters. This is the same adviser who wanted to drone-bomb migrants and asked whether international law could stop America from doing it. Now he's running operations without proper authority. Congress must investigate this abuse of power and restore constitutional chains of command.
