In a clear indication that the legislature is not completely preoccupied with the energy crisis, the Assembly observed a moment of silence in memory of a character from NBC's ''The West Wing.'' The Assembly leader, Kevin Shelley, a San Francisco Democrat, adjourned the session in memory of the fictional Mrs. Landingham, the president's secretary on the program. The character, played by Kathryn Joosten, died in a car accident in Wednesday night's episode. (Ms. Joosten is alive and well.) Mr. Shelley told the Assembly that Mrs. Landingham was a ''great American'' whose contributions to the nation ''were too numerous to count.'' Evelyn Nieves (NYT)
