[Bush Lied Millions Died]

Did someone finally read him the following statment

You have the right to remain silent anything you say can and will be used against you in a court of law. You the right to an attorney and to have an attorney present during any questioning. If you can not afford an attorney one will be appointed for you. Do you understand these rights as they have been explained to you?
