Chief Justice Allows White House Ballroom Construction, for Now

John Roberts, the chief justice of the United States, issued a one-sentence ruling this afternoon temporarily allowing President Trump to continue building a 90,000-square-foot ballroom in place of the old White House East Wing. The move gives Roberts and the other eight justices on the Supreme Court more time to decide whether the project can proceed.

Lower federal courts had ruled that Trump exceeded his authority by moving ahead with the construction without approval from Congress. But those decisions have been paused as the Supreme Court considers the president’s appeal.

In the meantime, the president has enlisted a team of 250 workers to install rebar and pour concrete at a breakneck speed. The Trump administration has argued there’s no point in halting a construction project that they said, as of last week, is 65 percent complete. They have also emphasized the national security imperative of upgrading a bunker beneath the ballroom.

The plans submitted by the White House to the Supreme Court include a set of stairs that had been included in earlier plans but not in the ones approved by the National Capital Planning Commission. Architects had derided the stairs because they did not lead to an entryway.

Trump seeks to prove his kingmaker status

The president is set to hold a rally tonight in Myrtle Beach in an effort to encourage South Carolina’s Republican voters to support his preferred candidate for Senate: Darline Graham.

The event comes four days before the decisive runoff election, and just three after she stumbled in a debate, raising questions about her lack of political experience and rattling some of her supporters. Privately, her opponent, Representative Ralph Norman, has expressed confidence in the race.

The contest poses a stark test for the president, who endorsed candidates who lost this week in Florida and Wyoming. Trump’s record in South Carolina is also uneven: He backed both Republican candidates for governor after his initial choice failed to take the lead.

Harry and Meghan’s U.K. move renews security questions

Much remains unknown about the upcoming return of Prince Harry and his wife, Meghan, to Britain, six years after they moved to the U.S. in a break with the royal family. One thing is clear: Many Britons have negative views about the couple, especially in comparison with Harry’s brother, William, and his wife, Kate.

Repeated threats against Harry and Meghan have made security a paramount issue for the couple, but it’s not clear what kind of protection they will receive. They lost their publicly funded security after stepping down from their royal roles, and armed details are tightly restricted in Britain.

A.I. is everywhere in China. Take a look.

It’s essentially impossible to walk down the street in Beijing without being bombarded by A.I. Some of it is genuinely useful; some is strange. But the Chinese public has been generally enthusiastic about its widespread use.

Join us on a stroll around China’s capital to see just how prevalent the technology has become. (Don’t jaywalk, though.)

Who could resist a good bookstore?

There’s something transporting about a truly great bookshop. The shelves welcome you with stories you love and others you feel like you ought to. And before you know it, you’re carrying out an armful of books.

On the latest episode of “The Book Review” podcast, my colleague MJ Franklin went to one of his favorite bookstores in New York to talk to the owner about what it’s like to run it. She told him staff members are always talking about how to create space for readers to connect with one another (couples have met and proposed to each other there).

Aging comes with surprises

Did you know that your feet might get longer and wider with age? I didn’t, until I read that my colleague Jancee Dunn recently had to go up a size. Experts told her it’s a common result of a descending arch, thanks to weakened muscles, ligaments and tendons.

A master of offshore art who didn’t know how to swim

Carlo Borlenghi was born in a small town on the eastern side of Italy’s majestic Lake Como. His father hoped he would take over the family plumbing business. Instead, Borlenghi became one of the world’s finest sailboat photographers, elevating images of racing yachts into an art form. He died this month at 70.

In Borlenghi’s photographs, the boats were often just a small detail in a panorama of heavy cloud banks, swirling turquoise ocean, fire-hose sprays of water and clusters of seabirds. See some of his images here, and read more about his life.

Have a gorgeous weekend.
