WHO is this MAsked MAN? REZKO?

Rezko had identified Obama as a good political target before he graduated from Harvard Law School. He was both the source of Obama's employment and of his largest political donations during his short political career. Rezko had no financial source apart from Auchi, his partner of over a decade. Rezko was also the source of the financing for Obama's $2.3 million mansion despite his having no clear source of funding apart from Auchi. What did he get from Obama in return?
