Bannon was the CEO of the 2016 Trump Campaign, was on Trump's National Security Council (!!), and started his apparently fraudulent charity while putting out pro-Trump movies a la Citizen's United. I think it counts as "campaign related", but I can see how you might disagree.
The other people 4 indicted were:
Flynn, who called the Russian Ambassador about sanctions during the transition and then lied to Pence and investigators about it. See Flynn thread, as he pled guilty a few times but is now is totally innocent because the FBI is mean.
George Papadopoulos, who lied to the FBI about talking to Russian agents during the campaign.
Mike Cohen, who lied to congress about the Trump Moscow projects and did two undisclosed payments to cover up two Trump sex affairs.
Roger Stone, who lied to congress about Wikileaks during the 2016 campaign.
I talked about the people who resigned/were fired during IG investigations here:

I'm not saying Biden is good. I do not expect to like Biden as president. But Trump was a spectacularly bad choice and the GOP has to own that, IMHO.
