He was busted early this morning for drunk driving. 
From the Perez Hilton Website:
The actor was in a celebratory mood, attending the Fox fall premiere party Monday night at LA club Area. A few hours later, he allegedly blew more than twice the legal limit when cops pulled him over on suspicion of DUI at 1:35 A.M.
Kiefer Sutherland was released from the Hollywood Police station at 5:42 this morning on $25,000 bail.
Eddiebear suggested that he was drinking heavily because of the prospect of having to work with Janine Garafolo.
Sounds about right.
UPDATE:
Mugshot here.

I’m just wondering about the whole Rufus thing.

I bet he was drinking because he has to work with Jeanine Garafalo this year.

That’s it!
Damn, I’m using that, eddiebear.
