WASHINGTON (CBSNewYork/AP) — Tim Kaine is shrugging off any possibility that he could be embarrassed by leaked emails.

COMPLETE CAMPAIGN 2016 COVERAGE

WikiLeaks has been taunting the Democratic vice presidential nominee on Twitter, saying it has a “surprise” in store for Kaine.

The organization has been posting thousands of stolen emails from Clinton’s campaign manager John Podesta. Cybersecurity experts told CBS News that the Russian hackers who infiltrated Podesta’s Gmail account are the same ones who targeted other Democratic groups.

Wikileaks posted taunting tweets directed at Kaine on Thursday and again on Sunday.

Kaine has questioned the authenticity of WikiLeaks’ releases and said the emails were hacked as are part of an effort by the Russian government to influence the presidential campaign.

“One of the emails that came up this week referred to me,” Kaine told CBS’ “Face the Nation” earlier this month. “It was completely inaccurate. And I don’t know whether it was inaccurate because the sender didn’t know what he or she was talking about it or it had been doctored.”

He continued, “Anybody who was going to try to cyber-attack and then try to destabilize an election, you can’t trust that they’re going to maintain scrupulous honesty about the content of what they’re dumping out for the world to see.”

In a recent interview with The Associated Press, Kaine said there’s nothing in his life or emails he’d be “overly embarrassed about” and said he’s determined not to be distracted.
