To Know or Not to Know

According to John Harris, President Obama knew of Blagojevich's quid pro quo expectations for the senate seat appointment that ultimately ended the Illinois governor's term. Obama previously had denied knowing any such thing.

Given Obama's ties to the Chicago political machine, the only thing that surprises me about this is that there has not been more evidence concerning the president's involvement already. I would guess this investigation will eventually grow to more directly relate to him.
