"Personnel management issues, also critical to policy development, portended a series of dramatic changes following the November 2018 congressional elections. Jim Mattis and his staff, for example, had a masterful command of press relations, carefully cultivating his reputation as a "warrior scholar." One story I was sure the media hadn't heard from Mattis was one told by Trump on May 25, as Marine One flew back to the White House after Trump's graduation speech to the Naval Academy. He said Mattis had told him, regarding Trump's appearing in a scheduled presidential debate just days after the Access Hollywood story broke in the press, that "it was the bravest thing he had ever seen anyone do." Coming from a career military man, that was indeed something. Of course, Trump could have been making it up, but, if not, it showed Mattis knew how to flatter with the best of them."
