Obama and Biden on war powers before something happened to them

Buzzfeed:

“The President does not have power under the Constitution to unilaterally authorize a military attack in a situation that does not involve stopping an actual or imminent threat to the nation,” Obama in 2008.


"I want to make it clear to you," Biden said speaking at a campaign event in Davenport, Iowa in December 2007. "I've drafted, with the help of 17 years I was the chairman of the Judiciary Committee or the ranking member. Ladies and gentlemen, I drafted and outline of what I think the constitutional limits have on the president in over the war clause. I went to five leading scholars, constitutional scholars, and they drafted a treatise for me, and it's being distributed to every senator. And I want to make it clear and I made it clear to the president, if he takes this nation to war in Iran, without congressional approval — I will make it my business to impeach him."
