Political advisers to President Bush may have improperly used their Republican National Committee e-mail accounts to conduct official government business, and some communications that are required to be preserved under federal law may be lost as a result, White House officials said Wednesday.

Of the 1,000 White House officials with political duties, 22 -- including Karl Rove, the chief political strategist -- have Republican National Committee accounts that are supposed to be used only for campaign-related work. But recent revelations that some officials have used those accounts for Bush administration business, including discussions of a plan to dismiss United States attorneys, has prompted a Congressional investigation.
