Did Rod Lie?

From the Rezko trial per the Chicago Sun-Times:

Newly unsealed court files in the Tony Rezko corruption case show that federal agents interviewed Gov. Blagojevich “on multiple occasions” and that the governor denied having conversations described in court by two key prosecution witnesses.

That raises the possibility that either the witnesses lied under oath or that the governor lied to federal agents about statements Blagojevich was said to have made, tying state business to support for his campaign.

This could begin getting very interesting indeed.
