Leahy can't even put together a coherent question and keeps interrupting Judge Roberts. What a baffoon!
"Excuse me, Mr. Roberts, I'm answering my questions here -- stop interrupting me with YOUR opinions."
Roberts' answer is that it depends on the particulars. Congress controls the purse strings, Roberts pointed out, so it can defund a war. Just as a curious Constitutional question, Leahy's question is interesting. I wish Roberts had a better answer. One would think that Congress does not give a president the authority to wage war in perpetuity. Indeed, Roberts might have mentioned the Revolutionary War, where Congress was poised to quit fighting and negotiate with England several times. Washington was always able to talk them out of it. That history (and I realize it predates the Constitution) perhaps gives us a lesson.
All that said, Leahy is still a tool, though he's not being as big a schumck as I expected him to be. Kennedy and Biden, I trust, will not disappoint.
