WikiLeaks made waves on Friday by releasing a huge trove of internal emails from the Democratic National Committee (DNC).

The hacked emails included what appears to be evidence of a concerted effort by DNC Chairwoman Debbie Wasserman Schultz and other party officials to thwart the presidential campaign of Sen.

According to CNN, U.S. officials briefed on the investigation into the compromised DNC emails now suspect Russian hackers are part of a bigger effort targeting political organizations and Washington, D.C., think tanks. 

On ABC's "This Week," Clinton’s campaign manager, Robby Mook, said the emails were leaked right before the Democratic National Convention “by the Russians for the purpose of helping Donald Trump,” citing “experts." Mook could not offer any evidence for the claim. 

Trump's campaign manager, Paul Manafort, dismissed the theory on the same program to host George Stephanopoulos when asked if there were any ties between Trump and the Russian government. 

“No, there are not," Manafort said. “That’s absurd. And, you know, there’s no basis to it.”
