The recent WikiLeaks publication of secret diplomatic cables between U.S. officials and contacts in other nations around the globe has painted a grim picture of the Russian government.

So it's the information they've gained from US government guys speaking on the phone or trough e-mails about. No actual source of it being trough. It's like me saying trough the phone to some guy that I'm a billionaire, however, U.S. still hasn't put me on that Forbes list.
