Of course they did. The $100,000 that these Russian companies spent on Twitter ads was very influential. It certainly carries more weight than the $141 million Hillary spent on ads or the $58 million Trump did. Don't you know that Russian ads are many times more effective than US ones. Especially online ones where people never ignore them routinely.
Facebook has refused numerous requests to actually show examples of these adverts. Twitter will likely do the same. Probably because of the supreme effectiveness of these ads makes them too dangerous to reveal to the public.
