The mayor’s call last week for District employees to turn in their cellular phones seemed a weak salvo in the Battle of the Budget. After all, how much could D.C. be spending on car and mobile phones?

Quite a lot, actually, judging by final numbers from the Sharon Pratt Kelly administration. The figures below are outstanding mobile-phone charges gleaned from the most recent list of the District’s unpaid bills, which includes the last quarter of fiscal ’94 and the first of fiscal ’95.

While posturing for headlines, Marion Barry should take note: The biggest culprit —by a long shot—is the mayor’s own office. Mr. Mayor, do yourself a favor: If your car phone rings, don’t answer.
