1804: Samuel Chase
Associate Justice of the Supreme Court

signer of the Declaration of Independence, Member of the Maryland Assembly and the Continental Congress; appointed to the Supreme Court by George Washington

President Thomas Jefferson, in what many historians view as an attempt to remove Federalists from the judiciary, encouraged the House to impeach the Supreme Court justice for political biases. Chase, among other things, was charged with making political statements to a Maryland grand jury. In a strictly partisan vote, Chase was impeached by the House but acquitted by the Senate on March 1, 1805.
