Everything you need to understand or teach Fear by Bob Woodward.
Bob Woodward, who formerly investigated the Nixon White House and Watergate, brings his investigative skills to uncovering what went on during the first two years of the Trump White House. By using the reports of "deep background" sources, Woodward puts together 42 chapters, each of which contains vignettes about Trump's functioning in the Oval Office. The author does not include much filler in between the harrowing accounts of Trump's indecision and incompetence in office. Instead, he reports mainly on meetings Trump conducts with his advisors.
