"Does it matter who broke in? Surely what's important is the content of what was released to the public," Putin said in an interview with Bloomberg News at an economic forum in Russia's far east. "That's what the discussion should be around. There's no need to try to distract public attention from the essence of the problem with questions of secondary importance connected with the search for who did it."
Asked by Bloomberg about the allegations, Putin laughed them off.
"I don't know anything about that," he said, chuckling in the interview with Bloomberg's John Micklethwait. "You know, there are so many hackers today, and they work with such minute precision, so finely." Putin added that hackers are able to "camouflage their activity under the activity of other hackers from other areas, other countries."
"In any case," he said, "we definitely don't do such things at a state level."
The FBI and security experts brought in to examine the DNC intrusion traced the attack to hacker groups they said are known to be linked to Russian intelligence services. CrowdStrike, the private cybersecurity firm hired by the DNC to investigate, said it identified two groups — dubbed Fancy Bear and Cozy Bear — that are believed to be controlled by Russia's foreign and domestic intelligence agencies, respectively.
Trump's campaign has strongly denied any links to the Russian government or untoward support for the country's policies.
The Republican nominee has seemed to enjoy sporadic attention shown him by Putin, such as when the Russian leader called Trump "colorful" and "very talented."
In July, Trump alluded to questions surrounding Clinton's use of a private email server while she served as secretary of state and jokingly said, "Russia, if you're listening, I hope you're able to find the 30,000 emails that are missing."
In the Bloomberg interview, Putin called allegations that Trump is backed by the Kremlin "nonsense."
Putin said that Russia had no stake in either the Democratic or the Republican nominee and criticized both for using what he called "shock tactics," seeming to refer to the two candidates' sometimes brutal attacks on each other.
"They are both intelligent people," he said. "They know how to push the right buttons."
"I don't think they're setting the best example," Putin said. "But that's the political culture of the United States. You have to take it as you find it."
