AUTHOR’S NOTE The reason to write this book could not be more obvious. With the inauguration of Donald Trump on January 20, 2017, the United States entered the eye of the most extraordinary political storm since at least Watergate.

Shortly after January 20, I took up something like a semipermanent seat on a couch in the West Wing. Since then I have c
