I strongly encourage you to sign this Moveon petition:
“Congress must force Vice President Cheney to respond to its subpoenas. If he continues to obstruct justice and disregard the rule of law, Congress has no choice but to begin impeachment proceedings against him.”
The fact that Moveon has gotten to this point is significant. The Democratic leadership listens to them, because they have to—and Moveon rarely moves too far away from the Democrats. Sign this and send it to everyone you know. Push Moveon to keep going.
