Update, 1:13 p.m.:

Big Head DC has received a copy of the official November 4, 1999 Illinois General Assembly transcript. The transcript proves that Sen. Barack Obama was absent from the assembly that day due to “personal business.” That date happens to fall near the same time period that Larry Sinclair, the Minnesota man who claims he used drugs and had a sexual encounter with Obama, alleges he met in secret with the politician.

A November 2007 Politico report indicates that Obama has repeatedly “dodged questions…about releasing papers from his eight years as an Illinois state senator, and his campaign has not answered records requests from the state’s two largest newspapers.”

Still, the publication noted, “Obama’s campaign has prodded Sen. Hillary Clinton (D-N.Y.) to make available additional records of her communications during her husband’s presidency.”

Later, during a Meet the Press appearance, moderator Tim Russert asked Obama about the missing records. “We did not keep those records,” Obama said at first.

Then Obama changed his answer, beginning with the statement, “Well, let me be clear.” He went on to say, “The stuff that I did not keep has to do with, for example, my schedule. I didn’t have a schedule. I was a state senator. I wasn’t intending to have the Barack Obama State Senate Library. I didn’t have 50 or 500 people to, to help me archive these issues.”

Obama’s campaign has not responded to requests for comment regarding the politician’s whereabouts on Thursday, November 4, 1999 or the weekend thereafter.
