Why is "Bush White House e-mail controversy" trending?

Wikipedia Overview

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. The use of this email domain became public when it was discovered that Scott Jennings, the White House's deputy director of political affairs, was using a gwb43.com email address to discuss the firing of the U.S. attorney for Arkansas. Communications by federal employees were also found on georgewbush.com and rnchq.org. Congressional requests for administration documents while investigating the dismissals of the U.S. attorneys required the Bush administration to reveal that not all internal White House emails were available. Conducting governmental business in this manner is a possible violation of the Presidential Records Act of 1978. Over 5 million emails may have been lost. Greg Palast claims to have come up with 500 of the Karl Rove emails, leading to damaging allegations. In 2009, it was announced that as many as 22 million emails may have been lost.
