According to US media reports, US President Biden said in an interview with the media on the 16th local time that he agreed that Russian President Vladimir Putin was a "killer" and that the latter would "pay a price" for interfering in the US general election. Biden's statement caused an uproar all over the world. According to US media, although the report of the office of the US director of national intelligence claims that Russia is trying to undermine Biden's candidacy because Russia believes that Biden's role as president is not in the interests of the Kremlin. But at the same time, the report said that there was no evidence that any foreign forces changed the vote of the US general election or otherwise disrupted the voting process.

After Putin spoke, a reporter asked Biden about this topic. When he was asked whether he agreed to have a dialogue with Putin, Biden refused to answer and turned away from the platform. Russian President's press secretary Peskov said on the 18th that "the remarks of the US president are very bad. He made it clear that he did not want to improve relations with our country. We will take this as the starting point.". Some media said frankly that Biden's remarks made the US and Russia, the former Cold War rivals, face the biggest crisis in many years.
