The ornament was made by Seattle artist Deborah Lawrence, who says she wanted to salute Rep. Jim McDermott, D-Wash., a longtime Bush foe who backs impeachment.
The nine-inch ball, submitted to the White House this fall, is covered with swirly red and white stripes and features a picture of McDermott. Tiny glued-on text salutes the impeachment resolution.
First lady Laura Bush asked members of Congress to pick artists to decorate ornaments for the tree. The ornaments are supposed to feature something special about each congressional district.
Sally McDonough, a spokeswoman for Laura Bush, called the ornament inappropriate.
