for POTUS handover their tax returns.

Thank you stillone~

The Russians use a lot of innocuous-sounding front companies to make their deals and launder money. They're very good at covering their tracks. So I don't think his tax returns will have any obvious links to the Russians.

It's more likely, IMHO, that he doesn't want to release his returns because he a) paid a ridiculously low tax rate and/or b) hasn't donated as much to charity as he claims.
