Oops. From the AP:
The White House has acknowledged recycling its backup computer tapes of e-mail before October 2003, raising the possibility that many electronic messages — including those pertaining to the CIA leak case — have been taped over and are gone forever.The disclosure came minutes before midnight Tuesday under a court-ordered deadline that forced the White House to reveal information it has previously refused to provide.
Among the e-mails that could be lost are messages swapped by any White House officials involved in discussions about leaking a CIA officer’s identity to reporters.
Before October 2003, the White House recycled its backup tapes “consistent with industry best practices,” according to a sworn statement by a White House aide.
Backup tapes are the last line of defense for saving electronic records.
Update: CREW, which filed the suit, has more on the White House’s filing.
