During a 90 minute interview with the Chicago-Tribune, Senator Obama revealed that his long-time friend and fundraiser, Tony Rezko, who was recently indicted for embezzlement, played a much larger fundraising role than previously disclosed. The Senator revealed that Rezko had raised $250,000 for his earlier campaigns.

Obama also elaborated on previous statements about his private real estate transactions with Rezko, saying they were not simply mistakes of judgment because Rezko was under grand jury investigation at the time of their 2005 and 2006 dealings. “The mistake, by the way, was not just engaging in a transaction with Tony because he was having legal problems. The mistake was because he was a contributor and somebody who was involved in politics.”

His first big contributor

When Obama launched his bid for the Illinois Senate in 1995, Rezko was his first substantial contributor. Obama said it was his “best guesstimate” that Rezko raised $10,000 to $15,000 of Obama’s roughly $100,000 collected for that race. Obama said he didn’t have more certainty because he didn’t then have the staff to maintain better campaign finance records.

Rezko helped bankroll all of Obama’s subsequent campaigns except his presidential bid. Rezko was on Obama’s campaign committee in his failed run against U.S. Rep. Bobby Rush and gathered between $50,000 and $75,000 of the estimated $600,000 raised in that race, Obama said.

Rezko also was on the finance committee for Obama’s 2004 U.S. Senate run. “My best assessment is that he raised $160,000 during my U.S. Senate primary,” he said, adding that those funds had been given to charity.
