Why would a case they said was open and shut now have a desperate "need" for "documents and witnesses"??? You should be angered that you were lied to.
Maybe Schiff shouldn't have lied to the America people for the past 3 years through his rotted out teeth. No one made him state on TV for 2 years that he had evidence of collusion that even Mueller couldn't find. No one made him give a phony rendering of the phone call in front of the American people. No one forced him to impeach without first having made a proper case.
Your angry that Schiff is a tool. You should direct that at the person responsible: Pencil neck himself.
