The Senate hearings have brought out the scope of Russian hacking to influence the campaign. But we do not know if Trump or his people knew of this and knowingly assisted the Russians in the cyber attacks and fake news. The experts tracking the Russian false news and twitter bots have said that Trump may have unknowingly spread the Russian fake news like the child porn pizza place connected to Hillary, and the false news that Obama and Cruz were not US citizens. He tweeted some of these and boosted Infowars a site that spread a lot of the Russian fake news (also possibly unknowingly).
