There's no question that secretly recorded phone calls of the ex-governor will be in play when an indictment comes down in upcoming days.
But what's been long forgotten is what happened in the early days of a corruption probe into the Blagojevich administration.
Federal agents sat down and interviewed a key witness: Rod Blagojevich. He was better known then as "Public Official A."
There was more than one interview (Blagojevich has said there were "two," a court filing references "multiple" interviews) but they nonetheless happened.
And one session happened with a court reporter in the room, getting everything down on the record, sources tell me.
It is a federal offense to lie to federal agents.
Among the questions in their sessions was whether Blagojevich promised access to state business in return for donations.
Blagojevich reportedly denied it, according to the filing.
Two government witnesses who testified at the trial of fund-raiser Tony Rezko last summer said under oath that the conversations took place.
Here's the filing (footnote on page 49) blago.pdf.
