Does the sentence mean that Mr. Trump's comments sound hollow? I don't think it means simply "looking bad."
Far from taking Washington by storm, America’s CEO is out of his depth. The art of political compromise is new to him. He blurs his own interests and the interests of the nation. The scrutiny of office grates. He chafes under the limitations of being the most powerful man in the world. You have only to follow his incontinent stream of tweets to grasp Mr Trump’s paranoia and vanity: the press lies about him; the election result fraudulently omitted millions of votes for him; the intelligence services are disloyal; his predecessor tapped his phones. It’s neither pretty nor presidential.
