A prominent fundraiser for Sen. Barack Obama and Illinois Gov. Rod Blagojevich was convicted Wednesday of fraud and money laundering after a high-profile federal trial provided an unusually detailed glimpse of the pay-to-play politics that has made Illinois infamous.

Antoin “Tony” Rezko, 52, showed no emotion as the jury delivered a mixed verdict that found him guilty of scheming with the government’s star witness to get kickbacks out of money management firms wanting state business, but acquitted him of charges that included attempted extortion.
