Many of the tales of controversy to emerge from the Trump administration have been abstract, or complicated, or murky. Whenever anyone warns about destruction of “norms,” the conversation quickly becomes speculative—the harms are theoretical, vague, and in the future.

This makes new Washington Post reporting about President Donald Trump’s border wall especially valuable. The Post writes about how Trump has repeatedly pressured the Army Corps of Engineers and the Department of Homeland Security to award a contract for building a wall at the southern U.S. border to a North Dakota company headed by a leading Republican donor.

The story demonstrates the shortcomings of Trump’s attempt to bring private-sector techniques into government. It shows his tendency toward cronyism, his failures as a negotiator, and the ease with which a fairly primitive attention campaign can sway him. At heart, though, what it really exemplifies is Trump’s insistence on placing performative gestures over actual efficacy. And it is a concrete example—almost literally—of how the president’s violations of norms weaken the country and waste taxpayer money.

In theory, Amazon is a site meant to serve the needs of humans. The mega-retailer’s boundless inventory gives people easy access to household supplies and other everyday products that are rarely fun to shop for. Most people probably aren’t eager to buy clothes hangers, for instance. They just want to have hangers when they need them.

But when you type hangers into Amazon’s search box, the mega-retailer delivers “over 200,000” options. On the first page of results, half are nearly identical velvet hangers, and most of the rest are nearly identical plastic. They don’t vary much by price, and almost all of the listings in the first few pages of results have hundreds or thousands of reviews that average out to ratings between four and five stars. Even if you have very specific hanger needs and preferences, there’s no obvious choice. There are just choices.

In 1957, a beach-ball-shaped satellite hurtled into the sky and pierced the invisible line between Earth and space. As it rounded the planet, Sputnik drew an unseen line of its own, splitting history into distinct parts—before humankind became a spacefaring species, and after. “Listen now for the sound that will forevermore separate the old from the new,” one NBC broadcaster said in awe, and insistent that others join him. He played the staccato call from the satellite, a gentle beep beep beep.

Decades later, we are not as impressed with satellites. There have been thousands of other Sputniks. Instead of earning front-page stories, satellites stitch together the hidden linings of our daily lives, providing and powering too many basic functions to list. They form a kind of exoskeleton around Earth, which is growing thicker every year with each new launch.

When Game of Thrones ended its eight-year run on Sunday, the series finale, titled “The Iron Throne,” received a largely negative critical response. Many writers pointed out that the show’s last season had given up on the careful character-building of Thrones’ early days—a problem that, in truth, had started a few years back. The result was a seemingly rushed conclusion where multiple characters made poorly justified decisions and important story lines felt only halfway developed.

The show made plenty of mistakes in its final episode, but among the most significant was Thrones’ abrupt and uncharacteristic turn to moralizing—and its use of heavy-handed allusions to 20th-century history to do so. Characters who were once morally complicated, whose actions fit within well-developed personal motivations and fueled the show’s gripping political drama, became mechanisms to bring the story to a hasty, unearned conclusion. Characters like Daenerys Targaryen and Tyrion Lannister—previously complex and fully formed—became, in “The Iron Throne,” mere tools in the service of a plodding message about the dangers of totalitarianism.

T

he call came in 2014, shortly after Easter. Four years earlier, Catrin Almako’s family had applied for special visas to the United States. Catrin’s husband, Evan, had cut hair for the U.S. military during the early years of its occupation of Iraq. Now a staffer from the International Organization for Migration was on the phone. “Are you ready?” he asked. The family had been assigned a departure date just a few weeks away.  

“I was so confused,” Catrin told me recently. During the years they had waited for their visas, Catrin and Evan had debated whether they actually wanted to leave Iraq. Both of them had grown up in Karamles, a small town in the historic heart of Iraqi Christianity, the Nineveh Plain. Evan owned a barbershop near a church. Catrin loved her kitchen, where she spent her days making pastries filled with nuts and dates. Their families lived there: her five siblings and aging parents, his two brothers.

Smith College’s annual commencement ceremony begins like any other: Graduating seniors at the women’s liberal-arts college are called up one by one to collect their diploma from the president. Perhaps some students exchange a wink with the regalia-clad honorary-degree recipients nearby as they stride across a platform overlooking the dorms they’d for years called home; others may pause to flip their cap’s tassel while blowing a kiss to the sea of parents who have long awaited this milestone commemorating their daughter’s metamorphosis from undergraduate to alumna.

Except the moment, technically, hasn’t happened quite yet: The name, degree, and accolades printed inside each padded holder seldom belong to the woman who receives it. They very likely belong, rather, to one of her nearly 700 classmates.

On the weekend before the opening gavel of what’s being dubbed the Harvard affirmative-action trial, a record-breaking 597 of my fellow members of the class of ’88 and I, along with alumni from other reunion classes, were seated in a large lecture hall, listening to the new president of Harvard, Lawrence Bacow, address the issue of diversity in the admissions process. What he said—and I’m paraphrasing, because I didn’t record it—was that he could fill five whole incoming classes with valedictorians who’d received a perfect score on the SAT, but that’s not what Harvard is or will ever be. Harvard tries—and succeeds, to my mind—to fill its limited spots with a diversity not only of race and class but also of geography, politics, interests, intellectual fields of study, and worldviews.

Uber is now a massive, publicly traded company. Anyone can buy Uber shares at a valuation of about $70 billion. This isn’t bad for a company losing billions of dollars a year, but it’s a fraction of the $120-billion valuation the IPO’s bankers initially floated. It’s roughly what private investors valued it at three years ago, when the company made $7.43 billion less revenue.

That is to say, there’s a large gulf between how venture capitalists saw the company and how a broader set of investors on the public market see it. Journalists and analysts have tried to explain this yawning gap. Maybe it’s because Uber stayed private too long, or because Lyft messed up ride-hailing IPOs, or because the timing was bad, or because the long shadow of corporate misbehavior has tarnished the brand. With $50 billion on the table, there’s plenty of blame to spread around.

President Donald Trump can only escalate. He cannot help it.

On Thursday night, he spread from his own presidential account a video of the speaker of the House, edited to splice together moments when she stumbled over her words, in an apparent effort to deceive people into thinking her drunk or ill. In 2016, Trump’s Russian supporters performed this service for him with faked videos of Hillary Clinton. Now he seems to have decided that if you want a dirty-tricks campaign done right, you must do it yourself.

At the same time, he has put the declassification powers of the presidency to work as part of a larger campaign of cover-up.

Trump directed his attorney general to declassify documents in an effort to depict Trump’s campaign as a victim of improper surveillance in 2016. Trump tweeted that the attorney general had “requested” these powers. That may even be true. But Trump has been demanding such an investigation of U.S. intelligence agencies since long before William Barr got the top law-enforcement job. Barr is compliant and complicit, but the idea is all Trump’s.

The artist Sarah Walker once told me that becoming a mother is like discovering the existence of a strange new room in the house where you already live. I always liked Walker's description because it’s more precise than the shorthand most people use for life with a newborn: Everything changes.

Because a lot of things do change, of course, but for new mothers, some of the starkest differences are also the most intimate ones—the emotional changes. Which, it turns out, are also largely neurological.

Even before a woman gives birth, pregnancy tinkers with the very structure of her brain, several neurologists told me. After centuries of observing behavioral changes in new mothers, scientists are only recently beginning to definitively link the way a woman acts with what's happening in her prefrontal cortex, midbrain, parietal lobes, and elsewhere. Gray matter becomes more concentrated. Activity increases in regions that control empathy, anxiety, and social interaction. On the most basic level, these changes, prompted by a flood of hormones during pregnancy and in the postpartum period, help attract a new mother to her baby. In other words, those maternal feelings of overwhelming love, fierce protectiveness, and constant worry begin with reactions in the brain.
