Donald Trump is not well. Over the weekend, he continued his weird obsession with a dead war hero. This time, his attacks on John McCain came two days after the anniversary of McCain’s release from a North Vietnamese prison camp. He tweeted this:

Spreading the fake and totally discredited Dossier “is unfortunately a very dark stain against John McCain.” Ken Starr, Former Independent Counsel. He had far worse “stains” than this, including thumbs down on repeal and replace after years of campaigning to repeal and replace!

And this:

So it was indeed (just proven in court papers) “last in his class” (Annapolis) John McCain that sent the Fake Dossier to the FBI and Media hoping to have it printed BEFORE the Election. He & the Dems, working together, failed (as usual). Even the Fake News refused this garbage!

The first Facebook message arrived when Heather Woock was packing for vacation, in August 2017. It was from a stranger claiming to be her half sibling. She assumed the message was some kind of scam; her parents had never told her she might have siblings. But the message contained one detail that spooked her. The sender mentioned a doctor, Donald Cline. Woock knew that name; her mother had gone to Cline for fertility treatments before she was born. Had this person somehow gotten her mother’s medical history?

Her mom said not to worry. So Woock, who is 33 and lives just outside Indianapolis, flew to the West Coast for her vacation. She got a couple more messages from other supposed half siblings while she was away. Their persistence was strange. But then her phone broke, and she spent the next week and a half outdoors in Seattle and Vancouver, blissfully disconnected.

A coast-to-coast FBI probe alleges that a network of celebrities, business executives, and other powerful figures is at the center of a massive bribery scheme to secure admission into some of the country’s most elite colleges, according to court documents unsealed earlier today.

Among the defendants are nearly three dozen parents whom federal prosecutors are charging with conspiracy and other crimes for allegedly using hefty sums of money to get their children into schools such as Yale, Georgetown, and the University of Southern California. Specifically, the newly unsealed court documents contend that these high-rolling parents—some of them public figures such as the actresses Felicity Huffman and Lori Loughlin, as well as Loughlin’s husband, the fashion designer Mossimo Giannulli—paid hundreds of thousands, and sometimes millions, of dollars per child to a fixer who would then use that money to allegedly bribe certain college officials or other conspirators to help secure the child’s admission.

Long before he got into politics, Donald Trump relished the power and reach of his Twitter feed. And not long after he took office aides recognized the damage that unvetted tweets could inflict, with the president using them to set policy, settle scores, and steer the national conversation.

Worried about misfires, aides have implored him to use social media more sparingly. At times, they’ve given Trump menus of pre-vetted tweets from which to choose. And they’ve held what some describe as interventions in the White House residence, with friends and family encouraging him to stop tweeting and praising him on days he’s shown restraint.

The push-and-pull has played out behind the scenes for the past two years. But if the last 72 hours have shown anything, it’s that staff still hasn’t figured out how to corral his social-media habit, and that as legal and political pressures mount, Trump is likely to turn more to Twitter to vent displeasure and discredit foes.

Last Tuesday, the Justice Department charged 50 people with involvement in an elaborate scheme to purchase spots in some of the country’s top schools. The tactics described in the indictment were complex and multipronged, requiring multiple steps of deception and bribery by parents and their co-conspirators to secure their children’s admission to the schools of their choice. The plot purportedly included faking learning disabilities, using Photoshopped images to make it seem as if students played sports that they did not actually play, and pretending that students were of different ethnicities in an effort to exploit affirmative-action programs. The alleged scheme was led by a man named William Singer, who called his business venture a “side door” into college. On Tuesday, Singer pleaded guilty to all charges.

Beto O’Rourke has been doing a lot of apologizing since entering the race for the Democratic presidential nomination just days ago. Among other things, the former Texas congressman has expressed regret for having made light of his negligent parenting, for the extent to which he had benefited from “white privilege,” and for having penned a gruesome murder story as a teenager. Given the mood of the Democratic Party’s activist base, however, I suspect all these will be considered venial sins in comparison to the fact that he once flirted with entitlement reform.

While O’Rourke’s exploits as a teenage hacker could be dismissed as youthful mischief-making, The Wall Street Journal reports that he called for raising the Social Security eligibility age and means-testing federal entitlements as recently as 2012, when he was in his late 30s, old enough and wise enough, presumably, to have reached a considered judgment on such important questions of public policy.

Whether they’re running for president or just hoping to hold on to their seats, Democratic lawmakers face growing pressure to endorse one of Bernie Sanders’s signature causes. “Doc, they keep coming—pressing me to sign onto Medicare for all,” a somewhat hesitant and confused congressman told me recently. “Should I?”

“It all depends what you mean by ‘Medicare for all,’” I said. He was hoping for a better answer than I had. About 70 percent of Americans say they support the idea—under which Medicare, the federal program that now provides health coverage for about 60 million seniors and disabled individuals, would expand to cover millions more people.

Yet Medicare for all is a messy concept. At least four different approaches to health reform could truthfully carry the Medicare for all label. Sanders’s plan is the best known, but it’s also the most politically impractical. It ignores the brutal history of repeated defeats for all Democratic health-reform proposals that try to abolish private health insurers.

Robert Bowers wanted everyone to know why he did it.

“I can’t sit by and watch my people get slaughtered,” he posted on the social-media network Gab shortly before allegedly entering the Tree of Life synagogue in Pittsburgh on October 27 and gunning down 11 worshippers. He “wanted all Jews to die,” he declared while he was being treated for his wounds. Invoking the specter of white Americans facing “genocide,” he singled out HIAS, a Jewish American refugee-support group, and accused it of bringing “invaders in that kill our people.” Then–Attorney General Jeff Sessions, announcing that Bowers would face federal charges, was unequivocal in his condemnation: “These alleged crimes are incomprehensibly evil and utterly repugnant to the values of this nation.”

In April 2016, Venus Lockett was about to give a speech at an event she’d volunteered for near her home in Atlanta. She was already stressed. The previous night, she had stayed up late making her presentation, and then deleted it by mistake. As she stepped up to the podium to give her remarks, she noticed that her words were slurring. She tried to speak into the mic, but the words that came out didn’t make sense.

A friend walked up and grabbed Lockett by the arm. A few people, noticing that something wasn’t right, walked Lockett to another room and called an ambulance. Lockett, who was 57 at the time and uninsured, didn’t know whether she could or should refuse the ambulance ride or decide which hospital it would take her to.

The American legal system pretends to marble-and-mahogany majesty, but is in fact often a rickety, underfunded contraption, run by overworked mortals who are sometimes incompetent and sometimes actually ill-intentioned. But even amid law’s cratered landscape, sometimes a specific case presents facts simply beyond belief; sometimes the “system” stands revealed as nothing more than one human being tormenting another because he can.

For me, such a case is Flowers v. Mississippi, a death-penalty appeal to be argued before the Supreme Court on Wednesday. The specific issue the Court will hear is whether, during a murder trial in 2010, a Mississippi prosecutor named Doug Evans deliberately used “peremptory challenges” to remove potential jurors because of race. If the U.S. Supreme Court agrees, then Flowers’s conviction for multiple murders in 1996 will be set aside.
