As reported by Censor.NET citing Reuters, Trump made his remarks at Mar-a-Lago, his seaside Florida resort where he is spending the Christmas and New Year's holidays while also interviewing candidates for administration jobs.
Trump has cast doubt on the findings of U.S. intelligence agencies that Russian hackers took information from Democratic Party computers and individuals and posted it online to help Trump win the election.
Asked by reporters if the United States should sanction Russia, Trump replied: "I think we ought to get on with our lives. I think that computers have complicated lives very greatly. The whole age of computer has made it where nobody knows exactly what's going on."
Trump said he was not familiar with remarks earlier on Wednesday by Republican Senator Lindsey Graham, who said Russia and President Vladimir Putin should expect tough sanctions for the cyber attacks.
"We have speed. We have a lot of other things but I'm not sure you have the kind of security that you need. But I have not spoken with the senators and I certainly will be over a period of time," he said.
The Obama administration plans to announce on Thursday a series of retaliatory measures against Russia for hacking into U.S. political institutions and individuals and leaking information, two U.S. officials said on Wednesday.
