A D.C. Council panel has lost deposition testimony collected in a probe of a dubious firetruck donation to a Dominican Republic town, sparking a rebuke from Attorney General Peter Nickles and a demand that the investigation end without a report.

The recorded testimony of two executive branch witnesses, Thorn Pozen and Robin Booth, was mislaid — or maybe copied over — by the council’s government operations committee. That panel, jointly with the judiciary committee, is investigating the donation of a firetruck and ambulance to Sosua, a town on the north Dominican coast.
