Peter Frampton: "What is the point of a subpoena if, when handed it, you can just say "No" and..."

28. Why not? It happened before. Here is what I found about it in wikipedia:

Inherent contempt

Under this process, the procedure for holding a person in contempt involves only the chamber concerned. Following a contempt citation, the person cited is arrested by the Sergeant-at-Arms for the House or Senate, brought to the floor of the chamber, held to answer charges by the presiding officer, and then subjected to punishment as the chamber may dictate (usually imprisonment for punishment, imprisonment for coercion, or release from the contempt citation).[10]

Concerned with the time-consuming nature of a contempt proceeding and the inability to extend punishment further than the session of the Congress concerned (under Supreme Court rulings), Congress created a statutory process in 1857. While Congress retains its "inherent contempt" authority and may exercise it at any time, this inherent contempt process was last used by the Senate in 1934, in a Senate investigation of airlines and the U.S. Postmaster. After a one-week trial on the Senate floor (presided over by Vice President John Nance Garner, in his capacity as Senate President), William P. MacCracken, Jr., a lawyer and former Assistant Secretary of Commerce for Aeronautics who was charged with allowing clients to remove or rip up subpoenaed documents, was found guilty and sentenced to 10 days imprisonment.[11]
