Papadopoulos: For lying about this: "In subsequent days Papadopoulos worked with Mifsud and Polonskaya to arrange contacts between the Russian Ministry of Foreign Affairs and the Trump campaign. In late April 2016, Papadopoulos emailed an unnamed Trump campaign "Senior Policy Advisor," stating "The Russian government has an open invitation by Putin for Mr. Trump to meet him when he is ready." At about the same time, Mifsud told Papadopoulos that the Russian government had "dirt" on Hillary Clinton in the form of "thousands of emails," which Papadopoulos then shared with Alexander Downer in a London bar days later."
Manafort and Gates: If your defense is that since Ukraine is an enemy of Russia, and therefore there can't be any pro-Russian agents there, I have bridges to sell you.

Cohen: Lying about business developments in Russia (money is always a nice motivator in crime).
Stone: Had contact with Russian state hackers about the DNC hacks.

Donald Jr wasn't indicted for anything, but he managed to incriminate himself all on his own volition on twitter: https://www.nytimes.com/interactive/2017/07/11/us/politics/d...
The most charitable interpretation of this whole thing is that the Trump campaign were too stupid to qualify as collusion (but I think they were fully aware), but were instead pawns: https://www.reuters.com/article/us-usa-trump-russia-senate/s...
