Archive Sues to Recover 5 Million Missing White House E-mails, The National Security Archive, September 5, 2007.

The National Security Archive today sued the White House seeking the recovery and preservation of more than 5 million White House e-mail messages that were apparently deleted from White House computers between March 2003 and October 2005....

"The Bush White House broke the law and erased our history by deleting those e-mail messages," said National Security Archive director Tom Blanton. "The period of the missing email starts with the invasion of Iraq and runs through the aftermath of Hurricane Katrina."
