The book is poised to include “stories and images never before shared with the public,” according to its publisher.

Donald Trump revealed this week that his youngest son, Barron Trump, learned about him being shot when he was at a tennis lesson.

During an interview with Fox News’ Mark Levin, Trump revealed his youngest son learned that his father had been shot while on the tennis court.

“He’s a good tennis player. And somebody ran up (and said), ‘Barron! Barron! Your father’s been shot,’” Trump recounted, adding that Barron reacted immediately: “He loves his father. He’s a good kid, a good student. And he ran, ‘Mom! What’s going on? What’s going on?”

Trump said his wife, former First Lady Melania Trump, was watching coverage of the July 13 rally in Butler, Pennsylvania, and saw the attempt on his life play out live. “She was watching it live. Can you imagine? And then I got up and let people know I was okay. Fight. Fight. Fight. But it was a big hit,” Trump said.
