First lady of the United States is a hard job. It’s not formally defined yet entails many demands; it has an impact on history but no formal powers; it’s the focus of all eyes, but people like to make it clear nobody elected you. Its locus is the East Wing, which the West Wing considers the silly place. You must be guided by tradition but be open to novelty so no one accuses you of being boring.

Melania Trump has been a figure of sympathy, at least in this space, lauded for her grace, elegance and stoicism. She’s married to a man who, emotionally and intellectually, is not exactly in the middle of the bell curve. She wound up in a job she never particularly wanted, in a time of unprecedented national division. She has done it pretty well. She has brought chic, American glamour and beautiful manners to the world’s capitals. (There was the “I Really Don’t Care Do U?” jacket, but at least that was spirited.) She humbly presented a gift in a Tiffany box to the Obamas on Inauguration Day, while her husband forgot to help her out of their car. She has self-control, and the independence to disagree with her husband -- when she said separating families at the border is no good, when she stood up for LeBron James after the president called him stupid. She’s slapped his hand away when he gropily attempts to portray normal unity. She’s put up with many scandals, some personally mortifying.

So it was a surprise to see her issue a hissy-fit of a statement about the deputy national security adviser, Mira Ricardel. “It is the position of the Office of the First Lady that she no longer deserves the honor of serving in this White House.” Yowza.

Granted, Ricardel’s public reputation suggests she’s quite a blunderbuss. But Mrs. Trump’s statement added to -- and included her in, for the first time -- the White House’s reputation for chaos, the sense that nobody’s in charge, that it’s all factions, head-butting and rumors about who’s going to get fired next. Wednesday Politico had a quote from an unnamed former White House staffer describing the atmosphere: “It’s like an episode of ‘Maury.’ The only thing missing is a paternity test.”
