Special counsel Robert Mueller submitted his final report to Attorney General William Barr Friday, signaling the end of his 22-month investigation into Russia and Trump's campaign.

Mueller did not recommend new indictments, crushing the predictions of many anti-Trump advocates who claimed Trump's closest allies, like Donald Trump Jr. and son-in-law and senior adviser Jared Kushner, could be indicted as part of Mueller's final act.

To most, including CNN legal analyst Jeffery Toobin, that meant good news for Trump and his inner-circle, proving they did not break the law. However, Beto O'Rourke must have not received the memo, telling supporters in South Carolina on Saturday that Trump is guilty of attempting to collude with Russia to undermine the 2016 presidential election.

What did Beto say?

Speaking in Charleston, South Carolina, O'Rourke claimed Trump "beyond the shadow of a doubt" attempted to collude with Russia.

"You have a president, who, in my opinion, beyond the shadow of a doubt, sought to, however ham-handedly, collude with the Russian government, a foreign power, to undermine and influence our elections," O'Rourke said, according to CNN.

"If you are wondering about collusion then when you saw the president of the United States standing next to leader of Russia on that stage in Helsinki, Finland, defending him and taking his word for it against our own intelligence community in our country, in George Will's words not mine, that is collusion in action," O'Rourke went on to claim. "Ultimately, I believe this will be decided at the ballot box in 2020 by you, by me, by all of us in this country."

O'Rourke's comments come as Congress awaits a briefing by the Justice Department on the "principle conclusions" of Mueller's investigation. The briefing is expected this weekend.

Almost immediately after Mueller submitted his final report to the Justice Department, O'Rourke, who is a former Texas congressman, called for the report's public release in the name of government transparency.
