'Iran' Sending Congressmen Packages?

The article only discloses what Rep. Steve Pearce received, CDs, and that they appeared harmless.

In recent weeks several Congressmen have received similar packages addressed from Iran but so far it hasn't been determined they are actually coming from there.

Overzealous warmonger? The 'anthrax terrorist' out of supplies? How is it they haven't listened to the CDs yet...could they contain something embarrassing for the Bushies? If that's the case we'll never know what's on them.
