President Barack Obama says the United States will take action against Russia or any other foreign government that tries to meddle in U.S. elections.
"I think there is no doubt that when any foreign government tries to impact the integrity of our elections...we need to take action. And we will," the president told National Public Radio in an interview.
The CIA has concluded that Russian hackers broke into the Democratic Party computers to leak potentially embarrassing emails about the Hillary Clinton presidential campaign with the apparent aim of helping Republican Donald Trump win last month's election.
Top White House officials say such a thing could not have happened without Russian President Vladimir Putin's involvement or direct knowledge.
Obama told NPR that there is still a "whole range of assessments" going on among U.S. intelligence agencies, and he is waiting for a final report on exactly who was involved and why they did it.
