The One America News channel confessed in 2019 that it was working with active Russian agent (Andriy) Andrii Derkach less than a year before President Donald Trump's administration revealed him to be working for Russian intelligence.
According to a tweet that is still visible on OAN's account, the network did "over a half dozen interviews with Ukrainian officials, including Ukrainian MP Andrii Derkach, pic shown."

The network did a series of propaganda films they called "documentaries," claiming it would prove that now President Joe Biden was embroiled in a Ukraine scandal that never existed. While conspiracy theorists continued to perpetuate the lies, Trump's intelligence staff concluded that Derkach was working with Russian intelligence in Ukraine.
Derkach was also named in the recently released report from the Office of the Director of National Intelligence that said Russian intelligence was working with Trump allies and conservative news outlets to promote false propaganda.
"A network of Ukraine-linked individuals—including Russian influence agent Konstantin Kilimnik—who were also connected to the Russian Federal Security Service (FSB) took steps throughout the election cycle to damage US ties to Ukraine, denigrate President Biden and his candidacy, and benefit former President Trump's prospects for reelection," said the report. "We assess this network also sought to discredit the Obama administration by emphasizing accusations of corruption by US officials, and to falsely blame Ukraine for interfering in the 2016 presidential election."
The report goes on to say that Kilimnik, Derkach, and their associates "sought to use prominent US persons and media conduits to launder their narratives to US officials and audiences. These proxies met with and provided materials to Trump administration-linked US persons to advocate for formal investigations; hired a US firm to petition US officials; and attempted to make contact with several senior US officials."
The report never names OAN but it's pretty clear that the network was among those targeted along with Fox News and The Hill's John Solomon, who spread lies about Biden and Ukraine.
