It was a low-key start to what could be an explosive trial that's expected to highlight Rezko's influence in Gov. Blagojevich's administration. Rezko, 52, who was a key adviser to and fund-raiser for Blagojevich, stands accused of shaking down millions of dollars in kickbacks and campaign contributions from companies seeking state pension business.
Obama's name didn't come up -- until a court security officer asked spectators in the overflow courtroom whom they were representing. A woman told him privately she was there for Obama.
"She was gathering information about the trial because there have been so many press inquiries," Obama spokesman Bill Burton said later, adding she won't be there for the whole trial.
