The claim is Russia went through a propaganda campaign to support Trump. This included them having teams of people on social media spreading false information, creating groups, etc. It also included the DNC hacks. Whether they just thought he would be better for them, thought an inexperienced leader would be easier to manipulate, or they just didn't like Hillary, who knows? They also (according to intelligence) preferred Bernie over Biden for 2020. Do with that what you will.
Votes weren't changed, they were influenced. This is why I say we don't know who would have won without the interference. There's no way to predict how votes would have gone. So, if that had been the end of it, then Trump is president and it isn't his fault....but he did say in one speech that someone should hack into Hillary's stuff (I think that was the phrasing, its been a while). Also the meetings his people had with Russian Agents. however, the investigation didn't find evidence of that...now there was a bit of obstruction and refusal to assist with the investigation...but the house didn't go after that, so whatever. The Russia probe in the end found that by legal definition Trump would have had to request Russia's assistance and understand that he owed them something back in return for it to be illegal. They concluded there was no evidence of an agreement of that sort.
Now, the "good news" is that when Russia tried the same thing leading into 2020 it was determined that we now spread so much propaganda ourselves that the Russian attempts at influence were generally falling flat. So yay. We now spread so much BS that it drowns out manipulative BS.
Not my president - I never said it. He was my president even if I was never happy about it. Seems a lot of people on the right are saying the same thing about now. Clinton had to work through an impeachment trial. If he did solicit aid from Russia, then he should have been impeached. The investigation was to determine that. If he had cooperated it would have been over faster with a lot less doubt, but that is just my opinion. As far as the media attacking him...the media is a business and the minute people stopped caring about it, they would have stopped reporting on it.
