I have a question as to the meaning/intent of the expression “contempt of Congress”. Congress to my learning and understanding is made of two bodies i.e. House of Representatives and the Senate. Question! Can “contempt of Congress” be based on only one of the bodies? If both bodies must be affected I can see where Holder can have a smug attitude.
