I think that the Russians were in there, but it doesn't mean other people weren't too.
Despite President-elect Donald Trump's repeated insistence otherwise, one of his top advisors insists Russia was behind computer hacking meant to influence the 2016 election -- and new evidence from intelligence officials makes it clear. Former CIA director James Woolsey told CNN Russia was involved in the hacks, but they may not have been alone.
Trump has insisted multiple intelligence agencies can't prove who was involved in the hack. But Woolsey said any disagreements between agencies were about how the hack was carried out, rather than who was involved.
Officials recently unveiled new "digital fingerprints" that point to Russian involvement. The keyboards used by the hackers featured Cyrillic characters. The software used also has metadata that points to Russia, CNN reports.
WATCH | Trump has insisted he knows something about the hacks that other people don't, which he will reveal on "Tuesday or Wednesday."
WATCH | Trump has also cast doubt on the intelligence community's consensus, comparing this to the misinformation that Iraq had weapons of mass destruction in the early 2000s.
WATCH | Incoming White House press secretary Sean Spicer criticized reporters for "jumping to conclusions" on the hack.
Russia's involvement with the hacks led President Obama to kick out 35 Russian diplomats and issue more sanctions. Putin did not respond in kind, which Trump later called a "great move."
