From the Sun-Times:

For the first time, Sen. Barack Obama put a figure Friday to the amount of campaign contributions that indicted political fund-raiser Tony Rezko raised for the senator’s campaigns, and the number — about $250,000 — was far more than he previously acknowledged.
“We believe we have identified all money that is traceable. … It’s hard for me to know precisely. I don’t have the capacity to go back and figure out who did he raise money from. There might be additional dollars,’’ Obama told the Chicago Sun-Times in an 80-minute interview that focused on his 17-year relationship with Rezko, who has become a lingering issue as Obama seeks the Democratic nomination for president.
