Senior Trump administration staffers, including Kellyanne Conway, Jared Kushner, Sean Spicer and Steve Bannon, have active accounts on a Republican National Committee (RNC) email system, Newsweek has learned.

The system (rnchq.org) is the same one the George W. Bush administration was accused of using to evade transparency rules after claiming to have “lost” 22 million emails.

Besides the unfortunate P.R. optics of Trump using a nonofficial email server in his White House after a campaign built on attacking a similar practice, there are other, more serious problems. First, obviously, is cybersecurity. Russian hackers didn’t harvest as much material from the RNC system as from the Democrats’, but the system was still hackable. Second is transparency. Trump and other Republicans throughout the 2016 campaign voiced concerns about the transparency of Clinton’s use of a “home-brew” personal email server in her basement. FBI Director James Comey called her email practices “extremely careless,” and the investigation and lingering taint of suspicion arguably cost her the election.

The chief effect of using the RNC server in the Bush years was to leave investigators who wanted to know more about the origins of the Iraq War in the dark—for years. It remains impossible to determine whether Bush staffers ever sent classified material over the RNC system.
