Former CIA director James Woolsey, an adviser to Trump on national security issues, told CNN's Jim Sciutto that determining who was behind the hacks is difficult, but that he believes the Russians -- and possibly others -- were involved.
"I think the Russians were in there, but it doesn't mean other people weren't, too," he said. "It's often not foolproof to say who it is because it is possible and sometimes easy to hide your tracks. There's lots of tricks."
Asked if Trump is playing the media with his comments on who was culpable, Woolsey said it was a "possibility," noting that Trump is an "expert in weaving around" on issues like this.
One official told CNN the administration has traced the hack to the specific keyboards -- which featured Cyrillic characters -- that were used to construct the malware code, adding that the equipment leaves "digital fingerprints" and, in the case of the recent hacks, those prints point to the Russian government.
But, despite an initial public assessment by the US intelligence community in October that Russia was behind the intrusions, Trump and his staff continue to voice doubts.
