A very stable genius: Donald J. Trump's testing of America - Philip Rucker & Carol Leonnig

A Very Stable Genius is based on hundreds of hours of interviews with more than two hundred sources, including Trump administration officials, friends and outside advisers to the president, and other witnesses. Most of the officials who spoke to us did so on the condition of anonymity to avoid retribution from the president and his allies or because they felt honor-bound not to publicly criticize a sitting president. But many of them, we found, were motivated to tell the truth for the benefit of history. Their statements speak for themselves.
