Canadian Prime Minister Jean Chrétien's aide has finally been forced to resign over her calling George W. Bush a "moron."

Mr. Chrétien comes from the left wing of Canada's governing Liberals and is uncomfortable with Mr. Bush's stance on many issues, including the threats to attack Iraq.

Mr. Chrétien, 68, developed a close friendship with President Clinton during his presidency and often golfed with him. But he is one of the few leaders of a close United States ally yet to be invited to spend time at Mr. Bush's private ranch in Texas.
