Taxpayers, who are being reimbursed for Ms. Linton’s travel, may never have known about that junket had she not decided to use a photo of herself alighting from the plane to show off her Hermes, Valentino and Tom Ford ensemble on Instagram. She then savaged a woman from Oregon who dared call the move “#deplorable.” As the clothes designers began distancing themselves, Ms. Linton apologized to America — in an interview with a Washington society magazine that ran a photo of her, in a ball gown, on the cover.

Mr. Mnuchin comes from a world where rich people get free stuff all the time. Now he is in a different world, one where taxpayers are on the hook. “We’re starting to see a pattern with Steve Mnuchin,” says Walter Shaub, former chief of the Office of Government Ethics, now at the Campaign Legal Center. “This is the tone from the top, that President Trump himself has set: Ethics doesn’t matter, and high positions of public trust come with perks.”

The Mnuchins, along with Jared and Ivanka, have lost no time establishing themselves as one of the most rapacious It couples in Washington. The “Moochin’ Mnuchins” were a hot topic on social media on Thursday, as commenters reviewed the pair’s outrages, the latest dubbed the “Love Jet.” Mr. Mnuchin was among the first administration grifters to draw attention from government ethics officials when he failed to disclose $95 million in assets, including houses in the Hamptons and Los Angeles and a New York City co-op, on his financial disclosure form.

An innocent oversight, he said. Then, in a media interview, he, first, acknowledged that as a cabinet member he couldn’t “promote anything that I’m involved in”; then, second, added, “but you should all send your kids to ‘Lego Batman,’” a movie he produced. He then found himself apologizing again, sort of, in a memo to the ethics office, saying, “It was not my intention to make a product endorsement.”
