One of my favorite books is A Treasury of American Scandals by Michael Fahrquhar. Although I'd read this book before Trump even became a candidate for the Presidency.

There is a section at the end which shares interesting points of trivia about each President.

For instance, Bill Clinton is the only President to have been a Rhodes scholar. James Madison, at 5' 4" was the shortest president. At 330 pounds, William Howard Taft was the fattest president. Steven Grover Cleveland was the only president to serve two non-consecutive terms. Jimmy Carter is the only President to have never appointed a Supreme Court Justice.

It occurs to me that this section needs to be updated.

Ronald Reagan is no longer the only divorced President. (Although he is the only President to have been divorced only once.) Bill Clinton and Andrew Johnson are no longer the only impeached Presidents, but they are the only ones to have been impeached once.
