President Trump is not a lifelong politician like the previous losers. They all had time to start “Foundations” and stuff as a way to hide their bribes. That way they could produce a very bland tax return that reveals nothing.
I don’t believe any of them had as complex tax return as Trump does either. Access to all his tax information would open up a lot of entities to attack.
I agree with your take on it, and I think there are many more issues involved here.
With the Left in the U. S. essentially adopting the tactics of terrorists, seditionists, and other “ists”, it’s no wonder Trump wants to remain somewhat secretive out of defense for his partners.
