The Framers did not intend the impeachment power to give Congress supremacy, in the form of being able to harass and paralyze the Courts or the president over policy differences, let alone raw political will. Nevertheless, Congress has acted, almost from the beginning, with selective contempt for the Constitution, both legislatively and in its employment of the impeachment power.

Take a step back from the current tempest in the Congressional teapot and consider the facts laid out in 1992 by Chief Justice William Rehnquist in Grand Inquests: the Historic Impeachments of Justice Samuel Chase and President Andrew Johnson. The Chief Justice published this very approachable book the year that William Jefferson Clinton beat President Bush the First. Taking his book as a guide to the subject and the actors, some focused searching on the internet yields plenty of historical data and documents. Consider just the first major impeachment, along with a prelude, at the dawn of the 19th Century.More
