hi clo,
this is the subject he keeps changing. but it keeps coming back. surely many dodgy transactions. some may involve russian oligarchs or other bad actors. who knows?
i don't know if a deal with putin will show up in his tax returns. if a deal exists, it involved the russians influencing the election.
if so, what did they get for it? plenty of possibilities. but i doubt it involves cash. putin wants to damage the us. so an investigation needs to find evidence of collusion, trump's agreement to do harm and such harm occurring.
but there's another narrative which may be just as likely. putin and trump actually share goals. let's say they both want to pick apart the EU, then putin may have acted without needing to collude.
