Washington, D.C. Apparent gaps in White House e-mail archives coincide with dates in late 2003 and early 2004 when the administration was struggling to deal with the CIA leak investigation and the possibility of a congressional probe into Iraq intelligence failures.
The gaps - 473 days over a period of 20 months - are cited in a chart prepared by White House computer technicians and shared in September with the House Reform and Government Oversight Committee, which has been looking into reports of missing e-mail.
Among the times for which e-mail may not have been archived from Vice President Dick Cheney's office are four days in early October 2003, just as a federal probe was beginning into the leak of Valerie Plame's CIA identity, an inquiry that eventually ensnared Cheney's chief of staff.
Contents of the chart - which the White House now disputes - were disclosed Thursday by Rep. Henry Waxman, a California Democrat who chairs the House committee, as he announced plans for a Feb. 15 hearing.
