"7 Blago questions for Obama."

From Politico:

1 – “Did you communicate directly or indirectly with Blagojevich about picking your replacement in the U.S. Senate?”....

2 – “Why didn’t you or someone on your team correct your close adviser David Axelrod when he said you had spoken to Blagojevich about picking your replacement?”...

3. “When did you learn the investigation involved Blagojevich’s alleged efforts to ‘sell’ your Senate seat, or of the governor’s impending arrest?”...

4 – “Did you or anyone close to you contact the FBI or U.S. Attorney Patrick Fitzgerald about Blagojevich’s alleged efforts to sell your Senate seat to the highest bidder?”...

5 – “Did federal investigators interview you or anyone close to you in the investigation?”...

6 – “When did you and Blagojevich last speak and about what?”...

7 – “Do you regret supporting Blagojevich?”...

More at the link. The key question is #4. It presumes he knew there was a sale going on. Does the criminal complaint not imply that he did? And if the answer to #4 is "no," what are we to think?
