A March 22, 2006, post to her weblog, Reidblog, archived by the Wayback Machine and titled “The official story,” links to Loose Change 9/11, a viral 80-minute web video originally released in 2005. Loose Change, which was produced in part by Infowars’ Alex Jones, alleged that the terrorist attacks on the World Trade Center were in fact planned by the US government. The central claims in Loose Change have been widely debunked.

“The fundamental question is: do you believe the official story of 9/11?” the post reads. “If you do, great. If you don’t, then everything that happened after that is called into serious question. Even if you’re agnostic, or you tend to believe that al-Qaida attacked the World Trade Center and Pentagon and that the government had no warning such a thing could happen, it’s worth taking a second look.”

Neither Reid nor MSNBC responded to requests for comment.
