Obama criticized Clinton expressly for failing to read the classified National Intelligence Estimate on Iraq's weapons capabilities, a report available at the time of her October 2002 vote authorizing the Iraq war. "She didn't give diplomacy a chance. And to this day, she won't even admit that her vote was a mistake - or even that it was a vote for war," Obama said.

"When it came time to make the most important foreign policy decision of our generation the decision to invade Iraq Senator Clinton got it wrong," Obama said.

He said that Sen. Jay Rockefeller, a fellow Democrat from neighboring West Virginia, had read the intelligence estimate as a member of the Senate Intelligence Committee and had voted against the war resolution.

Rockefeller, who is now chairman of that committee, endorsed Obama on Friday and campaigned with him on Saturday.

Rockefeller called Obama "brilliant" and "well grounded" and prepared to take the reins as commander in chief.

In fact, Rockefeller didn't just passively vote "yea" in the Senate. He gave a speech on October 10, 2002, prior to the vote, exhorting his colleagues to support the AUMF and the invasion of Iraq. In that speech, he made it clear that his vote would be in support of war, if it came to that:

Saddam Hussein represents a grave threat to the United States, and I have concluded we must use force to deal with him if all other means fail. That is the core issue, and whether we vote on it now, or in January, or in six months time, that is the issue we all have to confront.

War, if it comes to that, will cost money I dearly wish we could use for other domestic priorities, to address the very real needs that West Virginia and other states face in this tough economy. But ultimately, defending America's citizens from danger is a responsibility whose costs we must bear.
