Waxman focuses on the RNC emails

TPM Muckraker:

The RNC has said that the committee provides email addresses to White House personnel so that they can keep their official and political duties separate.

So what's the official/political breakdown for Karl Rove?

According to National Journal (not available online), Rove does approximately 95 percent of his emailing from his RNC address.

Think Progress says Waxman warns the RNC not to delete their emails:

Multiple congressional investigations have uncovered evidence that White House appointees regularly communicate using email accounts provided by the Republican Party. As CREW has argued, such activity violates the Presidential Records Act, which requires the White House to preserve such records. Today, House Oversight and Government Reform Committee Chairman Henry Waxman (D-CA) issued letters to the Republican National Committee and the Bush-Cheney ‘04 Campaign directing them to preserve all emails by and for White House officials, and to meet with the committee about the legal issues involved in conducting official government business using partisan email accounts.
