So he's a liar...He's still under investigation by the IRS.
Some of it was just taking advantages built into the system to extreme.
Either way, his income streams, profit(or loss) centers, and tax claims are incongruent with his self proclaimed wealth and business acumen. It is congruent with being a tax cheat, a mark for the underworld, a shytty businessman, and a possible money launderer.

I didn't expect his taxes to break any new ground.

... some said in another thread this would destroy any other president... and i agree, but this is Trump. This is nothing.
