Bush White House email controversy
During the 2007 Congressional investigation of the dismissal of eight U.S. attorneys, it was discovered that administration officials had been using a private Internet domain, called gwb43.com, owned by and hosted on an email server run by the Republican National Committee, for various official communications. The domain name is an abbreviation for "George W. Bush, 43rd" President of the United States.
