Trump could have released his tax returns and proven them wrong. Trump could have shown their speculation to be mere speculation, and used it as a cudgel to discredit their reporting on his campaign. The Times was far, far out on a limb.
But the Times bet correctly. Trump still isn’t releasing his returns. And here’s what that means: whatever is in his returns is worse than what the New York Times is telling the world is in his returns. The Trump campaign has decided it prefers the picture the Times is painting — a picture where Trump didn’t pay taxes for 18 years — to the picture Trump’s real records would paint.
It’s the cover up, not the crime.
