Back in July, Wikileaks published 20,000 emails that showed that Democratic Party leaders favored Hillary Clinton during the primary season. Additionally, in the final weeks before Election Day, John Podesta, Clinton's campaign chairman, had his email hacked and the contents were sent to Wikileaks.

Now, exactly one week after the election, the director of the National Security Agency (NSA) says these hacks came from a foreign nation.

"There should be any doubt in anybody's mind — this was not something done casually," NSA Director Admiral Michael S. Rogers said Tuesday. "This was not something done by chance. This was not a target that was selected purely arbitrarily, this was a conscious effort by a nation state to attempt to achieve a specific effect."
