WASHINGTON –E-mail records are missing for 51 of the 88 White House officials who had electronic message accounts with the Republican National Committee, the House Oversight Committee said Monday.

The Bush administration may have committed (emphasis mine) “extensive” violations of a law requiring that certain records be preserved, said the committee’s Democratic chairman, adding that the panel will deepen its probe into the use of political e-mail accounts.

The committee’s interim report said the number of White House officials who had RNC e-mail accounts, and the number of messages they sent and received, were more extensive than previously realized.

The administration has said that about 50 White House officials had RNC e-mail accounts during Bush’s presidency. But the House committee found at least 88.

The RNC has preserved e-mails from some of the heaviest users, including 140,216 messages sent or received by Bush’s top political adviser in the White House, Karl Rove. However, “the RNC has preserved no e-mails for 51 officials,” said the interim report, issued by committee chairman Henry Waxman, D-Calif.

The 51 include Ken Mehlman, a former White House political director who reportedly used his RNC account frequently, the report said.

“Given the heavy reliance by White House officials on RNC e-mail accounts, the high rank of the White House officials involved, and the large quantity of missing e-mails,” the report said, “the potential violation of the Presidential Records Act may be extensive.”
