WikiLeaks on Friday afternoon published a database of 2,060 documents it claims are emails from Clinton's campaign chairman, John Podesta.

"I don't think we can dig in documents dumped by WikiLeaks and just assume they're all accurate and true," Kaine said on CNN's "State of the Union." 

"Anyone who hacks in to get documents is completely capable of manipulating them." 

Kaine added that he has "no way of knowing" the accuracy of the documents but said previous hacks have been connected to the Russian government. 

"If that is, in fact, true, you cannot accept as gospel truth anything in this document." 

In the speeches that were leaked, Clinton, the Democratic presidential nominee, says she supports “open borders” and muses about how she is “far removed” from the struggles of ordinary Americans.
