I'm not saying there wasn't an investigation, but I'm not convinced by the evidence after reading that document. The biggest thing that I saw was the ad spend was very small (<$1M)
The Russians hacked the emails - How is it then a conspiracy theory? These things are all facts:
Trump asked the Russians to hack Hillary, and hours later they began probing the Clinton domains.
Russian government hacked Podesta
Russian government hacked the DNC
Russian government gave those emails to Wikileaks to hurt Hillary / boost Trump and they were weaponized explicitly to do so (e.g. the Podesta release coming hours after the President was on tape bragging about grabbing women by the pussy)
Russian businessmen, closely linked to the government spent millions of dollars on a social media campaign to boost Trump
Trump's campaign took several meetings with Russians offering help with the election, including explicit meetings offered as "Part of the government's assistance to the Trump campaign" and then lied to the press and the government when asked about those meetings
Trump's campaign manager gave private polling data to several Russians, including a probable spy
Trump dangled pardons for his team if they didn't cooperate with the investigation
Trump pardoned those people who didn't cooperate with the investigation
Trump's team changed the entire GOP platform to be more friendly to Russia
Trump's transition team took clandestine meetings to promise to remove sanctions that were in place for the above activity.
Trump's son-in-law offered to take meetings in the Russian embassy to be out of range of US intelligence.
So far as I can tell, the "Hoax" that people are adamant about refers to the Mueller finding where they couldn't prove that any of the above was coordinated - And it very well might not have been! - but to say that it was a hoax that Russia helped Trump win is so silly.
