I'm on my phone right now so I can't dig up all of my sources but it's not just the CIA. 17 intelligence agencies all said the same thing. So did private security companies, including Russia's own Kaspersky lab. Guccifer 2.0 is a cover for a Russian hacking group called APT28. It's unfortunate that there are so many American citizens here who are willing to let a foreign mole be president, and to allow a foreign government to dictate policy to the United States. They're as bad as the Zionists who want the US to be Israel's lapdog. At least I'll get the satisfaction of seeing Trump either get impeached or arrested for treason sooner or later. Then someone qualified and patriotic, like Pence, can be President.
Hopefully nobody here works in the government or critical infrastructure. You don't want to get a visit from the FBI, now do you?
