House panel holds Clinton IT aide in contempt. So what does this mean? Probably nothing other than more Kabuki Theater. They have the power to arrest but the GOP will never have the balls to use it.
In 1821, the Supreme Court upheld Congress’s right to hold people in contempt and imprison them. Without this power, the court ruled, Congress would “be exposed to every indignity and interruption, that rudeness, caprice, or even conspiracy, may mediate against it.” Later, in a 1927 case arising from the Teapot Dome scandal, the court upheld the Senate’s arrest of the brother of a former attorney general — carried out in Ohio by the deputy sergeant at arms — for ignoring a subpoena to testify.
