Here is why we should not worry about Trump's taxes.

Whether or not all presidents in the past have produced their tax forms is NOT the standard to be met by Donald Trump.  The law requires a summary report and nothing more.  Trump's summary report was 140 pages long.  And that was present at the beginning of his campaign.  Nothing else is required.  

Understand that the IRS has the oversight responsibility for Trump,  NOT the House Committee.   He owns 546 businesses and is under audit 24/7.  If he was a tax cheat,  we would have known this decades ago.  

The matter is really that simple.  End of discussion.  Case closed.
