Rauner already has been airing a one-minute version of the ad featuring a snippet of one conversation between Blagojevich and Pritzker. Never played in court, the wiretapped conversations obtained by federal agents and first reported and released by the Tribune on May 31 feature Blagojevich and Pritzker discussing possible scenarios to fill the U.S. Senate vacancy of Barack Obama, who had just been elected president in November 2008. At the time, it was widely known that Blagojevich’s administration was under federal investigation.
