WASHINGTON Senator Bernie Sanders spoke out in a Senate floor speech yesterday against the nomination by President Bush of Michael B. Mukasey to be the attorney general. The attorney general must be a defender of our constitutional rights We need an attorney general who can explain to the president what the Constitution of this country is all about. We need an attorney general who does not believe the president has unlimited powerI have concluded that Michael B Mukasey would not be that kind of attorney general. That is why I will vote against his confirmation. Sanders Senate floor statement reiterated concerns he had outlined on October 22, when he became the first senator to announce his intention to vote against confirming Mukasey.
