I don't really have much more to add to this. Democrats and Republicans need to demand, in a bipartisan voice, that Donald Trump publicly release the last 25 years of his taxes, publicly, unredacted, and without delay.
That is the very first thing that should happen right now. The American people never got to see where he got his money before the election, he promised once he wasn't being audited anymore that he would release them, but that was obviously just another in a long list of lies from Donald Trump.
Call your reps and demand they take action to release his tax returns.
