• The publication date was moved up because Comey's firing by Trump remains hot in the news as special counsel Robert Mueller continues his investigation.
• The topic can be expected to cause a frenzy on the tour.

In Washington, Axios co-founder Mike Allen will moderate a conversation with Comey on April 30 at 7 p.m. (Lisner Auditorium, 730 21st St. NW), at an event presented jointly by Politics and Prose Bookstore and Axios.

• That will be Comey's only D.C. event during the tour, organizers said.

The publisher's announcement says Comey will "explore what good, ethical leadership looks like and how it drives sound decisions."

• "Using examples from some of the highest-stakes situations in the past two decades of American government, Comey will share yet-unheard anecdotes from his long and distinguished career."

• April 15: ABC News "20/20" special at 10 p.m.: interview with chief anchor George Stephanopoulos.
