Hayden is the only person ever to head both the National Security Agency (NSA) and the CIA. He says, “I would lose all respect for a whole bunch of foreign intelligence agencies if they weren’t sitting back, paging through the emails” of Clinton.
He adds, “Once you’ve set it up [as she did], nobody has to be stupid, lazy, unintelligent—it’s gone bad. You’re going to end up with information on this private server that just shouldn’t be there, let alone all the questions about preserving government records. […] How much energy would I expend if I were still director of the National Security Agency and someone told me I could get access to the unclassified email server of [Russian Foreign Minister] Sergei Lavrov? I’d move heaven and Earth to do that. And here you’ve got these private, intimate conversations by a senior official of the US government sitting out there in what I would call an unprotected environment.”
Hayden was appointed head of the NSA by President Bill Clinton and then head of the CIA by President George W. Bush. (USA Today, 2/24/2016)
