The White House e-mail controversy is starting to permeate the traditional media.  US News gave CREW's take on the potential illegality: 

News that administration officials are buying separate private E-mail accounts to avoid using the internal system, coupled with reports that aides have often used GOP E-mail accounts, is drawing heat from public interest groups. One, the Citizens for Responsibility and Ethics in Washington, or CREW, claims the practice could be illegal.

According to CREW, the Presidential Records Act appears to require that internal documentation be kept and that it should be handled in official channels. The separate accounts are outside those channels.

"It appears that White House staff members routinely violated the law by using RNC E-mail accounts for official business," said CREW's Melanie Sloan.
