There is absolutely no doubt that Russia interfered with US elections, but the extent to which it did remains unknown. I have read some conspiracy theories in American media which stipulated that Trump's visit to Russia in the early 90's (or late 80's, don't remember) was basically the first step in planning a large-scale overthrow of US democracy, and the next almost 30 years Russia was just waiting for the right opportunity to strike. As wild as it is, at this point in history I wouldn't rule this out as a possibility, though a very very wild one.
Also, the story with Maria Butina offering sex for government jobs is pretty hilarious and cringe, as it is something I would expect a Russian spy woman do. This is textbook Russian behavior. It's even funnier when you consider how recently one our politician said that Russian women should not sleep with foreigners during the World Cup, but I guess it's ok for Maria Butina to sleep with Americans because it's for the MOTHERLAND.
And it's funny to see the media's reaction this meeting. American media is bashing Trump as a traitor, yet his approval rating hit all-time high. Meanwhile Russian media talked about this summit as a pinnacle of Putin's statesmanship and ability to negotiate even with the toughest opponents, celebrating Putin as the sole person suited to guide Russia.
Please, give me another world to live in.
