President Trump’s public airing of grievances with John Kelly was perhaps an inevitable clash between two temperamentally similar but philosophically different alpha males.
With Twitter as his Excalibur, the president takes on his doubters, powered by long spells of cable news and a dozen Diet Cokes. But if Mr. Trump has yet to bend the presidency to his will, he is at least wrestling it to a draw.
Reince Priebus, who was fired in July, was the first senior administration official known to have been questioned by Robert Mueller’s investigators.
Mr. Kelly, the new chief of staff and a retired Marine general, is seeking to calm the chaotic churn around the president but not to directly control his behavior.
Christopher Ruddy, the chief executive of Newsmax Media, blamed Mr. Priebus for the botched rollout of Mr. Trump’s travel ban, among other stumbles.
