From The Washington Post:

It's true that in Washington, adversaries often wind up drinking together after hours. But when insiders at the FBI saw that Sen. Ted Stevens had RSVP'd "yes" to last Friday's annual director's holiday bash, the hunters couldn't quite conceive of partying with the prey. FBI agents raided the Alaska Republican's home less than five months ago as part of a sprawling corruption probe.

Every member of Congress is invited to the party, but Stevens was among those who had replied to say he'd be attending. But the embattled senator must have gotten cold feet: He was a no-show at the packed party, where handcuffs and holsters abound.
