In Michael Wolff's "Fire and Fury: Inside the Trump White House," professionals preparing to work with Trump were struck by the reality of his limited knowledge. They realized that, aside from a few specific areas, particularly construction, he seemed to lack a deep understanding across most topics they expected a leader to grasp. This led to concerns about his qualifications and ability to effectively govern.

The professionals' encounter with Trump's apparent ignorance highlighted a significant gap in his expertise, raising questions about his preparedness for the high-stakes environment of the White House. As they reflected on his capabilities, it became clear that his lack of mastery in essential subjects could impact decision-making and the overall functioning of his administration.
