The university president offered a new twist on exactly what happened with that mix-up in September, during a discussion with students, Lydia DePillis reports for Bwog:

Bollinger abandoned the pretense that the Iranian leader was asked not to speak because of “security concerns.” New version of events: he was informed on a Wednesday morning that Dean Anderson had invited Ahmadinejad while working in a small group setting at the UN to speak Friday morning. The President’s office couldn’t get a line of communication that would have assured him that Ahmadinejad would consent to a question and answer period, which Bollinger said was essential for this event to have academic merit. Especially considering Ahmadinejad had, one night earlier, implied that the Holocaust did not occur. “Are you unfathomably ignorant, or are you brazenly insulting?” PrezBo asked rhetorically.
