On August 16, 2020, Trump retweeted audio purportedly between Biden and former Ukrainian President Petro Poroshenko from a February 18, 2016 recording.

The video had already been described by US intelligence officials as part of a Russian campaign to attack and spread conspiracy theories against Trump’s 2020 opponent, Joe Biden.

The excerpt of the retweeted conversation centers on the ouster of Ukraine’s chief prosecutor, who had previously investigated the owner of a Ukraine energy company where Biden’s son, Hunter, once held a board seat. During the Obama administration, Biden led the charge to oust the prosecutor in the first place, with backing from several European allies, because of his failure to pursue corruption cases.

The account that originally tweeted the recording was suspended.

Trump has also tweeted a video about Biden flagged by Twitter for being misinformation, and in another instance, had his account restricted for spreading misinformation about COVID-19.
