Moscow spread "misleading or unsubstantiated allegations" about the eventual winner, Joe Biden, according to a US government report.
But it said no foreign government had compromised the final results.
Russia called the allegations of election interference "baseless".
"The conclusions of the report... are confirmed solely by the confidence of the intelligence services of their self-righteousness," the Russian embassy in Washington said in a statement. "No facts or specific evidence of such claims were provided."
The US is expected to impose sanctions on Russia as soon as next week over the report's conclusions, three sources told Reuters news agency.
US President Joe Biden has said that his administration is preparing a harsh response after American security agencies reported that Russia attempted to interfere in the 2020 US elections in favor of his opponent, Donald Trump.
ReplyDeleteIn an interview with the ABC news channel published on Wednesday, Biden was asked by Chief Anchor George Stephanopoulos whether he thought Russian President Vladimir Putin was “a killer.”"Mmm hmm, I do," Biden replied.
He added that he had previously warned his counterpart in Moscow that the US would potentially take action if it found evidence of Russian interference in the election. "He will pay a price," Biden said. "We had a long talk, he and I… I know him relatively well. And the conversation started off, I said, 'I know you and you know me.' If I establish this occurred, then be prepared."
