President Barack Obama hit at Russia and President Vladimir Putin during his final end-of-the-year press conference.

Obama stopped short of blaming Putin directly for hacks that interfered with the US presidential election, but he still pointed his finger in that direction.

“The intelligence that I’ve seen gives me great confidence in their assessment that the Russians carried out this hack,” he said.

Questions surrounding Russian interference in the election have become a central focus in recent days amid reports that a CIA assessment concluded Russia interfered in the US election with the specific goal of aiding Trump’s campaign. It was reported Friday that the FBI supported the CIA’s findings.
