WASHINGTON (AP) _ The House ethics committee said Thursday that Rep. Bud Shuster, chairman of the Transportation Committee, committed ``serious official misconduct'' through his actions with a lobbyist and his acceptance of improper gifts. But the panel took no action beyond a letter of disapproval.

``By your actions you have brought discredit to the House of Representatives,'' the Committee on Standards of Official Conduct wrote Shuster, R-Pa., who accepted the letter in a negotiated end to the case.

No action will be required by the full House as a result of the negotiated settlement, the committee said.
