His question follows a federal investigation into Russian-linked cyber attacks and an intelligence report linking the Kremlin to election-related online interference that promoted Donald Trump and right-wing conspiracy theories in an attempt to discredit Mr Biden.
Asked whether he believes Mr Putin is a “killer” in a pre-taped interview that aired on Wednesday, the president responded: “I do.”
“The price he’s going to pay, you’ll see shortly,” he said.
Mr Biden recalled meeting Mr Putin, during which he reportedly told him that he “doesn’t have a soul”: “I wasn’t being a wise guy.”
“He looked back at me and said, ‘We understand each other’,” Mr Biden said.
A report released on Tuesday from the Office of the Director of National Intelligence assessed that Russia sought to interfere with the 2020 presidential election with an expansive social media and online influence campaign similar to an operation from 2016.
The newly declassified report also said that a network of Ukraine-linked individuals connected to Russian intelligence relied on “prominent US persons and media conduits to launder their narratives” alleging “corrupt ties” among members of Mr Biden’s family with Ukraine.
That 2020 misinformation campaign was aimed at “denigrating President [Joe] Biden’s candidacy and the Democratic Party, supporting former President [Donald] Trump, undermining public confidence in the electoral process, and exacerbating sociopolitical divisions in the US,” according to the report.
Mr Biden said he had warned his Russian counterpart about a potential response from the US during a call in January.
“He will pay a price,” Mr Biden said. “We had a long talk … and the conversation started off, I said, ‘I know you and you know me. If I establish this occurred, then be prepared.’”
