Trump doesn't know anything. ...Trump's own words and conduct ...and his comments on many issues ...show how appallingly ignorant he is. - David Cay Johnston

I... watched Trump run briefly in 2000 for the nomination of the Reform Party... during that brief campaign Trump declared he would become the first person to run for president and make a profit. ...For the 2016 run, a large share of Trump's campaign money was spent paying himself for the use of his Boeing 757... in addition to his smaller jet, his helicopter, his Trump Tower office space, and other services supplied by Trump businesses.

Just as there is an underground economy of gardeners and handymen and petty merchants who get paid in cash and pay little or no taxes, there is also an underground economy among the super rich that lets them understate their true income and overstate their tax deductions.

Trump has... been sued thousands of times for refusing to pay employees, vendors and others. Investors have sued him for fraud in a number of different cities. But among Trump’s most highly refined skills is his ability to deflect or shut down investigations. He also uses threats of litigation to deter news organizations from looking behind the curtains of the seemingly all-wise and all-powerful man they often refer to as The Donald.
