Russian President Vladimir Putin said he doesn't know who hacked the e-mails of U.S. Democratic Party-affiliated organizations but added that the Russian government had nothing to do with it.
Putin said it may be impossible to find who is responsible for seizing copies of the e-mails but asked, "does it even matter who hacked this data?"
Putin, speaking before the start of the Group of 20 meeting of major economies in China that will be attended by U.S. President Barack Obama and many other world leaders, said the important thing is "the content that was given to the public."
The hacked e-mails were released by the activist group WikiLeaks in July and showed bias by the Democratic National Committee (DNC) for presidential nominee Hillary Clinton over rival Bernie Sanders.
Also hacked was a computer network used by Clinton's campaign and the Democratic Party's fundraising committee.
The scandal led to the resignation of the DNC's chairwoman and three other top officials.
Clinton has said the cyberattack involved Russian intelligence services, and some officials suggested the Kremlin is trying to influence the U.S. election in favor of Republican candidate Donald Trump.
But Putin said: "We have never interfered, are not interfering, and do not intend to interfere in [U.S.] domestic politics."
Russian-U.S. relations hit a post-Cold War low in 2014 over Moscow's interference in Ukraine.
