Antoin Rezko (born 1955) is an American businessman and convict, and former friend of (and major fundraiser for) Barack Obama.
Rezko was largely a fundraiser for the Illinois Democratic and some Republican politicians. After becoming a major contributor to Rod Blagojevich's successful election for governor, Rezko assisted Blagojevich in setting up the state's first Democratic administration in twenty years and as a result he was able to have business associates appointed onto several state boards. Rezko and several others were indicted on federal charges in October 2006 for using their connections on the state boards to demand kickbacks from businesses that wished to engage in dealings with the state. While the others pleaded guilty, Rezko pleaded not guilty and was tried. He was found guilty of 16 of the 24 charges filed against him and on November 23, 2011, he was sentenced to 10.5 years in prison.[1]
