From a New York Times review by David Greenberg of the book by Peter Baker and Susan Glasser titled “The Divider: Trump in the White House 2017-2021”:

“His job wasn’t to get things done but to stop certain things from happening, to prevent disaster.” This line from Peter Baker and Susan Glasser’s detail-rich history of the Trump administration, “The Divider: Trump in the White House, 2017-2021,” technically applies to his first secretary of state, Rex Tillerson. But in truth it describes any of several dozen beleaguered helpmates to the former president, whose propensity for petulant rage kept Washington in a fit of indignation and the White House in a mode of perpetual damage control for the better part of four years. Comprehensively researched and briskly told, “The Divider” is a story of disasters averted as well as disasters realized.
