The Wall Street Journals right-wing editorial page has written another blistering editorial slamming President Donald Trumps erratic and self-destructive behavior.
In a Tuesday op-ed, the Journals editors excoriated the president for sending out tweets that attacked London Mayor Sadiq Khan and that undermined his own case for his proposed travel ban.
When it comes to his fight with Khan, the Journal editors were appalled that Trump would bash the London mayor less than a day after his city suffered from a deadly terrorist attack.
World leaders who stoop to attack municipal politicians in foreign cities look small, not that we can recall a precedent, they wrote. If Theresa May has an opinion about Bill de Blasio shes kept it to herself, though the Prime Minister was compelled to say Mr. Khan is doing a good job. Its wrong to say anything else. In a humiliating coup de grace, the mayors office put out a statement saying he has more important things to do than respond to Mr. Trumps social-media insults.
