If you live in America today, the one historical fact you are most likely to have heard is that former President Trump is the first U.S. president ever to face criminal charges.

What is not as well-known is how many previous presidents came close – or might have come close — to confrontation with the U.S. criminal justice system.

Unique as he is in many ways, Trump is not the first president to gaze out the White House windows and wonder if one day he might wake up behind bars.
