Congress has heard extensive testimony about how Mr. Gonzales’s Justice Department has become an arm of a political party, choosing lawyers for nonpartisan positions based on politics, and bringing cases — including prosecutions that have put people in jail — to help Republicans win elections.

Mr. Gonzales’s repeated false and misleading statements to Congress are also impeachable conduct. James Iredell, whom George Washington would later appoint to the Supreme Court, told North Carolina’s ratification convention that “giving false information to the Senate” was the sort of act “of great injury to the community” that warranted impeachment.

The United States attorneys scandal is also the sort of abuse the founders worried about. Top prosecutors, most with sterling records, were apparently fired because they refused to let partisan politics guide their decisions about whether to prosecute. Madison, the father of the Constitution, noted in a speech to the first Congress that “wanton removal of meritorious officers would subject” an official to impeachment. . . .

IF Bush does not make Gonzo go, the Congress must.
