Witness Ali Ata (above, running from photographers) was the last-minute addition to the Tony Rezko trial, but his testimony may prove to be the most significant in bolstering the government's case.
Ata testified he gave Rezko more than $100,000 in cash bribes, that he got his state post after holding fund-raisers for Gov. Blagojevich and that Rezko helped Ata secure a state lease after Ata made Rezko a partner in the land deal.
He continues his testimony on cross examination Monday.
