The Bush White House, already recognized as the most secretive in history, used laptop computers and other communications devices paid for by the Republican National Committee to conceal questionable activities from investigators and circumvent the law.

The laptops, used alongside official White House computers, provided a way for Bush political guru Karl Rove (above) to work "off the books" and send communications that bypassed traditional channels and avoid the tracking systems used in the West Wing.

Writes Tom Hambuger of the Los Angeles Times [1]:

When Karl Rove and his top deputies arrived at the White House in 2001, the Republican National Committee provided them with laptop computers and other communication devices to be used alongside their government-issued equipment.

The back-channel e-mail and paging system, paid for and maintained by the RNC, was designed to avoid charges that had vexed the Clinton White House — that federal resources were being used inappropriately for political campaign purposes.

Now, that dual computer system is creating new embarrassment and legal headaches for the White House, the Republican Party and Rove's once-vaunted White House operation.

Democrats say evidence suggests the RNC e-mail system was used for political and government policy matters in violation of federal record preservation and disclosure rules.

In addition, Democrats point to a handful of e-mails obtained through ongoing inquiries suggesting the system may have been used to conceal such activities as contacts with lobbyist Jack Abramoff, who was convicted on bribery charges and is now in prison for fraud.

Democratic congressional investigators are beginning to demand access to this RNC-White House communications system, which was used not only by Rove's office but by several top officials elsewhere in the White House.

The prospect that such communication might become public has further jangled the nerves of an already rattled Bush White House.
