In 1797, articles of impeachment were found against William Blount, a Senator. The misdemeanors were not charged as being done in the execution of any office under the United States. He was not charged with misconduct in office, but with an attempt to influence a United States Indian interpreter, and to alienate the affection and confidence of the Indians. After the impeachment was known, but before it was presented to the Senate, the Senate expelled him, resolving “that he was guilty of a high misdemeanor entirely inconsistent with his public trust and duty as a Senator.”
In 1804, John Pickering, Judge of the District Court of New Hampshire, was removed for, — 1. Misbehavior as a judge; and amongst other causes, 4. For appearing drunk, and frequently, in a profane and indecent manner, invoking the name of the Supreme Being.
In 1804, Judge Chase was impeached and tried for arbitrary, oppressive, and unjust conduct, in delivering his opinion on the law beforehand, and debarring counsel from arguing the law; and for unjust, impartial, and intemperate conduct in obliging counsel to reduce their statements to writing, the use of rude and contemptuous language, and intemperate and vexatious conduct.
