The Supreme Court said today that President Trump’s executive order limiting birthright citizenship had violated the 14th Amendment of the Constitution. The justices, in a 6-to-3 decision, reaffirmed the long-held principle that children born on U.S. soil are American citizens.

The ruling blocked Trump’s effort to prevent babies born to undocumented immigrants and temporary foreign residents from automatically becoming Americans. Chief Justice John Roberts — who was joined in the majority by all three liberals, as well as conservative justices Amy Coney Barrett and Brett Kavanaugh — cited the views of the lawmakers who approved the 14th Amendment: “Citizenship, then and now, was the right to have rights — to freely participate in our political community,” he wrote.

In dissent, Justice Samuel Alito called the ruling a “serious mistake” that opened the door to those he called “birth tourists.” On social media, the president called the Supreme Court’s decision “too bad for our Country,” and urged Congress to take up the issue with legislation. My colleagues explained why that’s unlikely.

The justices allow bans on trans athletes in girls’ sports

The Supreme Court also announced today that it was upholding two state laws that bar transgender athletes from girls’ and women’s sports teams. The 6-to-3 decision means that all 27 states with such restrictions — nearly every red state in the country — will most likely be allowed to maintain their laws. It could also put pressure on states without bans.

The case centered on two transgender plaintiffs — a college student who wanted to compete on a women’s track team, and a high schooler who recently won a state shot put title — who argued that the laws violated the Constitution’s guarantee of equal protection. However, in the majority opinion, Kavanaugh wrote: “Allowing a biological male athlete to compete on a girls’ team necessarily displaces or disadvantages a female athlete.”

The court also lifts spending limits on political parties

In another 6-to-3 decision along ideological lines, the Supreme Court’s conservative majority removed restrictions on how much political parties can spend in coordination with candidates. The ruling further expanded the power of big money in American politics, and delivered a major victory for Republicans.

At issue was whether the federal limits on such spending — called coordinated party expenditures — violate the First Amendment. Kavanaugh, writing for the majority, said the court’s campaign finance precedents required it to strike down the restrictions. In dissent, Justice Elena Kagan wrote that the ruling was a recipe for corruption: “With no limits on coordinated expenditures,” she wrote, “the party can serve as the candidate’s checking account.”

Lawmaker says depression led to his monthslong absence

Thomas Kean, a House Republican from New Jersey, returned to Capitol Hill today after disappearing from the public eye for months with almost no explanation. He revealed in a speech on the House floor that he had been hospitalized for depression.

“Many people think it is feeling sad,” Kean said. “But depression is so much more than that. It is physical, it is emotional and until you experience it yourself, it is difficult to fully understand how powerful this illness can be.”

Today’s Colorado primaries offer another test of the left’s power

In three of today’s biggest primary elections, Colorado Democrats will be choosing between a Washington veteran and an opponent seeking to take advantage of the rising left-wing energy within the party. In Denver, for example, a House race pits Diana DeGette, a 15-term incumbent, against the 29-year-old Melat Kiros, who has framed her campaign around her support for the Palestinian cause.

Follow along with the results here as they arrive later this evening.

Serena Williams returns with grit

Nearly four years after retiring from tennis as one of the sport’s all-time greats, Serena Williams, now 44, returned to singles action today at Wimbledon.

Her first match back ended in defeat to Maya Joint, a 20-year-old from Australia. But the American superstar put on a show, battling from behind and displaying flashes of her old magic. Andy Roddick, the retired tennis star, said: “If this is a stress test for whether Serena can play at this level, she can.”

More from Wimbledon: Naomi Osaka showed up to her first match wearing a couture-level outfit modeled on a traditional kimono.

What 250 years of American food innovation brought us

Since the nation was founded this week in 1776, the foods that define American cuisine have shifted many times, influenced by imports and technology. James Hemings, an enslaved man who worked at Monticello, borrowed an early version of mac and cheese from the French. And Cheetos arose from surplus military cheese powder.

My colleague Kim Severson, a food writer, consulted with historians and created a decade-by-decade tour of the most important innovations that shaped the American diet. Take a look.

Look at these dogs go

One after another, hundreds of dogs charged up and over mounds of sand before jumping into a pool along with their owners. That was just the start of a four-mile canine obstacle course in the rolling green hills of Anniston, Ala.

The dogs climbed derelict cars, dashed over mounds of tires and splashed through muddy streams. It took the fastest teams just over 40 minutes to reach the finish. Huskies and German shepherds were well represented, but a few corgis, mini Aussies and Boston terriers also joined in on the fun. See our photos from the event.

Have a spirited evening.
