Actually, the White House was hacked two weeks ago. [1] Not much is officially known, some think that the hackers managed to penetrate a lot of their systems (some employees leaked info before the announcement).
Surely you are not claiming that there is no possible connection? if/once the Drupal Web server was hacked, the hackers could not possibly have served malware to admin users, or reached into other machines?
