WATCH: Putin opposition leader says he can show Paul Manafort’s links to the Kremlin

Alexei Navalny, a fierce critic of Russian president Vladimir Putin, posted a video on Thursday claiming to prove ties between onetime Donald Trump campaign chairman Paul Manafort and the Kremlin, the Moscow Times reports.

In the video, Navalny traces Manafort’s link to Russian oligarch Oleg Deripaska, whom the opposition leader alleged acted as an intermediary between the former Trump associate and associates of Putin.

Deripaska is the Russian metal tycoon who was offered “private briefings” by Manafort two weeks before then-candidate Trump secured the Republican nomination. Manafort had a $10 million annual contract with Deripaska before he was indicted on charges of money laundering and conspiracy as part of special counsel Robert Mueller’s investigation.

According to Navalny, there's a trail — through a "self-described 'sex huntress'" — that places Deripaska and Russia’s Deputy Prime Minister Sergei Prikhodko together in August 2016, a month after Manafort offered the Russian oligarch briefings on the campaign.

"[It’s] because these briefings were actually for Putin, the Kremlin, the Federal Security Service," Navalny charges in the video.
