Hillary Clinton: Possible Russian Interference in Election 'a Concern'

Clinton spoke to reporters Monday aboard "Hill Force One."

"We are facing a very serious concern. We've never had a foreign adversarial power be already involved in our electoral process, with the DNC hacks. We've never had a nominee of one of our major parties urging the Russians to hack more," said Clinton.

She continued, "I think it's quite intriguing that this activity has happened around the time [Donald] Trump became the nominee. And look, he very early on allied himself with [Russian President Vladimir] Putin's policies."

Clinton, speaking to reporters aboard her new campaign plane, dubbed Hill Force One, said this "credible report" on the probe, which the Post says is being coordinated by the U.S. director of national intelligence, shows that we need to be "on guard to protect our electoral system at all levels and we have to make it clear that we're not going to let anyone interfere with decisions of the American people."

"Listen, does it even matter who hacked this data?" he said. "The important thing is the content that was given to the public."

Clinton described Putin's response as a serious concern. "From my perspective, having met with and watched Putin over the years, when I saw his response to that question, it was very clear he's quite satisfied with himself," she said.

"It is stunning that we are facing this. And especially from a foreign power," said Clinton.

Clinton, whom Trump has accused of not having the stamina to be president, brushed off his attacks.
