As you may have heard or observed firsthand, Donald Trump has been in quite the mood over the last week or so, which may or may not have something to do with the Democrats flipping the House and threatening to rummage through his tax returns. Immediately following the midterms, he treated the nation to a nearly 90-minute meltdown in which he called a reporter a “terrible person” and “an enemy of the people,” told a black female journalist that she was being racist for asking him about racism, and vowed to attack any newly elected representatives even thinking about attempting to exercise congressional oversight. On Friday, before boarding Marine One, he snapped at CNN correspondent Abby Phillip (also black, also female), telling her that her question about acting Attorney General Matthew Whitaker was “stupid” and that he’d seen her “ask a lot of stupid questions.” In France, where he skipped an event commemorating the end of World War I because of rain, he was reportedly irritable for the entire 43 hours, fuming at President Emmanuel Macron for denouncing “nationalism”—which Trump took as a personal insult—and appearing “sullen” during the leaders’ bilateral meeting on Saturday. After returning from the trip, he launched into a furious, multi-tweet tirade against France on the anniversary of its 2015 terrorist attacks that killed 130 people. But as it turns out, Macron wasn’t the only world leader forced to deal with cranky POTUS this week, according to a new report from The Washington Post:

As he jetted to Paris last Friday, President Trump received a congratulatory phone call aboard Air Force One. British Prime Minister Theresa May was calling to celebrate the Republican Party’s wins in the midterm elections—never mind that Democrats seized control of the House—but her appeal to the American president’s vanity was met with an ornery outburst.

Trump berated May for Britain not doing enough, in his assessment, to contain Iran. He questioned her over Brexit and complained about the trade deals he sees as unfair with European countries. May has endured Trump’s churlish temper before, but still her aides were shaken by his especially foul mood, according to U.S. and European officials briefed on the conversation.

Trump has never been known for his diplomatic skills—berating Australia shortly after taking office in 2017 comes to mind—but that he couldn’t even hold it together to let May flatter him during a routine phone call suggests this “very stable genius” has become even more unglued.
