I didn't really understand why the Senate wouldn't seat him last week when the session opened.

IMO the Democrats didn't want to be tainted by the association with Gov. Blagojevich.

The law says that Obama's vacated Senate seat should be filled by a candidate appointed by the Governor of Illinois. Blagojevich had not yet been tried or impeached when he named Burris, so his appointment was perfectly legal. No one in all this process has even implied that Burris is guilty of any illegal or even underhanded dealings in regard to this seat, so the objection cannot be about him.

Besides, they need another Democrat in the Senate. I'm glad they finally rallied behind him.

Glad to see this is sorted out and we can move on. We have more important things to be concerned about.
