For those trying to make something out of the NY Times tax story, even the Times admitted they could not find any connection to Russia. They found nothing illegal. They insinuated illegality but only if you interpret the returns the way they did. Again, since his lawyers prepare and review his returns it is unlikely they put their names an anything illegal.
And while Trump signed his taxes, even if there are mistakes he is not going to jail and he won't be executed as some hope. He will be assessed a penalty and he will have to pay it.
The NY Times story is a non-event. It is basically, rich man pays taxes. I have to second what Dodger12 wrote, someone broke the law by revealing Trump's tax information. If it was government employees, either in the IRS, from the Mueller team, or from the SDNY, they should be sent to prison for the longer sentence allowed by law - which is 5 years. There was a time when stuff like this was considered a serious matter. But Democrats now use these dirty illegal tricks as a matter of practice.
