摘要

DONALD TRUMP seems to think he can best every challenge by insulting the challenger. It worked splendidly during the presidential campaign. But America's institutions are not political foes. As an investigation led by Robert Mueller into possible links between Russia and Mr Trump's presidential campaign grinds on, the president has flung ever more insults in the direction of law enforcement. His actions risk inflicting great damage on the country he leads.
