Hillary Clinton’s campaign manager Robby Mook suggested on Sunday that the DNC emails leaked last week were an effort from the Russians to help out Republican presidential nominee Donald Trump.

“What’s disturbing to us is that experts are telling us Russian state actors broke into the DNC, stole these emails, and other experts are now saying that the Russians are releasing these emails for the purpose of actually of helping Donald Trump,” Mook said on CNN’s “State of the Union.”

“I don’t think it’s coincidental that these emails were released on the eve of our convention.”

When asked what evidence there is that the Russians are behind this, Mook responded with, “We need to let the experts speak on this.”

Trump’s campaign then used Mook’s statements to attack Clinton’s dirty politics, saying she is a candidate who “will do anything to win.”

Trump senior communications adviser Jason Miller said in a statement “What a joke.” “This shows that Hillary Clinton will do and say anything to win the election and hold onto power in the rigged system.”

Donald Trump Jr. also bashed Mook’s comments later on “State of the Union.”

“It just goes to show you their exact moral compass. I mean they’ll say anything to be able to win this. This is time and time again, lie after lie,” said Trump Jr. “It’s disgusting. It’s so phony. I watched him bumble through the interview.”

Donald Trump Jr. also added “These lies and the perpetuating of nonsense to try to gain some political capital is outrageous and he should be ashamed of himself. If a Republican did that, they’d be calling for people to bring out the electric chair.”
