CNN/YouTube Debate: "Obama Challenges Clinton on the War"

Chris Cillizza (WaPo):

Obama, as promised, just went on the offense against Clinton over the war.

After Clinton referenced a letter sent by a Pentagon official that castigated her for asking questions about a withdrawal plan, Obama used an unrelated question to take on Clinton.

"It's terrific that she is asking for plans from the Pentagon," said Obama. "The time for us to ask how we are going to get out of Iraq is before we went in....That is something too many of us failed to do."

This is the first time Obama has directly taken on Clinton over the war. Let's see if she finds a way to hit back.
