- money laundering through Deutsche Bank
- quid pro quo for a Moscow tower development
- secret mail servers
- Trump as a "Russian agent"
- incriminating piss tapes
And many other topics which don't immediately come to mind but can be easily googled. For two years, these are the stories we were all told were just about to drop.
If for those years, the claim had been "Trump and Russians may have worked together to take out Facebook ads, push bogus articles through troll accounts on Twitter, and phish Clinton aides" nobody would have given a shit. Yet even this set of underwhelming claims probably exceeds all that the Mueller investigation suggests could allege to have taken place at maximum.
