A Very Stable Genius: Donald J. Trump's Testing of America by Philip Rucker and Carol Leonnig:
Another episode startled Trump’s advisers on the Asia trip. As the president and his entourage embarked on the journey, they stopped in Hawaii on November 3, to break up the long flight and allow Air Force One to refuel. White House aides arranged for the president and first lady to make a somber pilgrimage so many of their predecessors had made: to visit Pearl Harbor and honor the twenty-three hundred American sailors, soldiers, and marines who lost their lives there.
The first couple was set to take a private tour of the USS Arizona Memorial, which sits just off the coast of Honolulu and straddles the hull of the battleship that sank into the Pacific during the Japanese surprise bombing attack in 1941. As a passenger boat ferried the Trumps to the stark white memorial, the president pulled Kelly aside for a quiet consult.
“Hey, John, what’s this all about? What’s this a tour of?” Trump asked his chief of staff.
