Three time Pulitzer Prize-winning journalist Thomas Friedman, about Trump’s refusal to release his tax returns: During the campaign he promised to release them after the I.R.S. finished auditing him. Then, after he was elected, Trump said, sorry, not going to release them ever. And nothing happened. Trump, I am reliably told, has actually said to people close to him, “Can you believe I got away with that?”Once Trump saw that he could get away with not disclosing his tax returns, he knew he could get away with anything. He knew that once he compromised the G.O.P., even its evangelical wing, into giving him a pass on his taxes, they’d roll over for anything — sex with porn stars, endless lying, trashing the F.B.I., coddling Putin. Once you erase a big red line, it’s hard to start enforcing others…………….Because there must be something very important in them that he wants to keep hidden. Maybe it’s just the embarrassment that he is not as rich as he claims, or, maybe, it’s something more fundamental — like how dependent he is on Russian oligarchs for financing, so much so that Putin has leverage on him. Whatever the reason, though, when Trump saw he could get away with hiding them, he knew he could break any rule, tell any lie and violate any presidential norm — and he’s done just that.
