Rand Paul challenges Sec. John Kerry on War Authority against ISIS

Senator Rand Paul and Sec. John Kerry get into a much needed and slightly heated debate on war authority. Things start to get really good around 4:29:

KERRY: We have some of the most extraordinary self-imposed restraints on our checklists…for where and when and how we might use force. Even where we’ve been authorized to use force and you need to review that…

PAUL: There’s a very important restraint and that’s the Constitution it says Congress initiates war. You went to war in Libya without Congressional authority. You have now been at war for five months without constitutional or Congressional authority.

KERRY: We did not go to war in Libya. If that’s how you look at these..I mean, uh…This term of “war…”

Sen. PAUL: I forgot that was “kinetic action?”
