It seems at least some people have looked at Gore's speech and found it "factually challenged."

Gore compounds his misstatement by repeating a false claim about the recently released report on 9/11,

For example, according to the just-released Congressional investigation, Saddam had nothing whatsoever to do with the attacks of Sept. 11. Therefore, whatever other goals it served -- and it did serve some other goals -- the decision to invade Iraq made no sense as a way of exacting revenge for 9/11.

The UPI originally made this claim in a July 23 article, and later was forced to retract it on July 29 after the report had been released and did not contain any information about Iraq. According to UPI,

Prior to the report's publication, a person who had read it told UPI that it showed U.S. intelligence agencies had no evidence linking Iraq to the 9-11 attacks or to al-Qaida. In fact, the issue is not addressed in the declassified sections of the report.
One other person who has seen the classified version of the document told UPI subsequently that the Iraq issue is not addressed in the still-classified section, either. "They didn't ask that question," the person said.

Notice, by the way, that the UPI was apparently used by a source to plant a false story ahead of the release of the 9/11 report. And it worked -- the main thing the former Vice President seems to know about the report is this false story.
