First, a quick refresher about what happened in the Bush administration. In March 2007, eyes were on then-Attorney General Alberto Gonzales after the administration unexpectedly fired eight U.S. attorneys. Congress (recently taken over by Democrats) investigated the firings, alleging that the administration had dropped the prosecutors for political reasons.
Over the course of the investigation, it came out that some White House officials had conducted White House business over private email accounts set up on a server through the Republican National Committee. The White House later admitted that some internal White House emails conducted on the RNC server might have been lost.
Democrats in Congress accused the administration of purposefully circumventing recordkeeping processes, while the White House said staffers were supposed to use the RNC emails solely for political affairs, not official business. Comparing the Bush and Clinton email scandals is not exactly apples to apples, but there are some similarities.
We looked back at media coverage at the time, and Williams has a point that it didn’t cause the same level of hubbub as the Clinton email scandal. Though to say there was "zero press coverage" is an exaggeration -- even allowing for a bit of hyperbole.
