Over the weekend, President Donald Trump grew increasingly irritated as media coverage portrayed him as inattentive to the devastation on the U.S. territory of Puerto Rico. And so, he engaged in a now standard form of online catharsis: He sent out a series of off-key tweets in which he seemed to blame the hurricane-ravaged island for its own fate. When it was all done, Trump came off looking not only inattentive towards Puerto Rico’s plight but also unconcerned. The insecurity that he felt about that earlier coverage has only intensified, aides and confidants say, with some conceding that the president has himself to blame.
