President Trump will nominate Eugene Scalia, son of late Justice Antonin Scalia, to be the next labor secretary, the president announced via Twitter Thursday evening.

A source close to Scalia earlier Thursday confirmed to NPR that the president had offered Scalia the job and that he accepted.

Scalia, 55, is a partner at the law firm Gibson Dunn & Crutcher in Washington, D.C., where he handles cases related to labor and employment.

Mark Morgan, acting head of Customs and Border Protection, said Thursday that the Trump administration's new asylum rule, unveiled earlier this week, is being rolled out as a small "pilot" and that officials expect it to be blocked in court.

The rule is a major change in U.S. asylum law. It denies asylum protection to most migrants arriving at the Southern border unless they first apply in a country they passed through on the way.

Most days, 25-year-old Chavonne can push her student loan debt to the back of her mind.

Between short-term office jobs in the Washington, D.C., area, she drives for Uber. But once in awhile, a debt collector will get hold of her cellphone number — the one she keeps changing to avoid them — and it all comes back fresh. "I'll be like, 'Oh no!' " she says. "It's a sad reminder that I owe somebody money!"

In April, she got another reminder when the government seized her tax return.

All this for a degree she never finished.

Researchers are prescribing exercise as if it were a drug in a study that aims to see if it can prevent Alzheimer's disease.

"We are testing if exercise is medicine for people with a mild memory problem," says Laura Baker, principal investigator of the nationwide EXERT study and associate director of the Alzheimer's Disease Research Center at Wake Forest School of Medicine.

Good news came out from the Centers for Disease Control and Prevention Wednesday: Preliminary data shows reported drug overdoses declined 4.2% in 2018, after rising precipitously for decades.

A U.S. Navy warship called the USS Boxer took down an Iranian drone in the Strait of Hormuz on Thursday, President Trump said, adding, "The drone was immediately destroyed." A senior Iranian official has denied that the country lost a drone.

"The Boxer took defensive action against an Iranian drone," Trump said, giving details about the encounter at the start of a flag presentation ceremony at the White House. He said the drone had closed to about 1,000 yards from the U.S. ship, "ignoring multiple calls to stand down."

One of the rarest birds in New Zealand is having its best breeding season in decades, potentially doubling the population.

The orange-fronted parakeet, known locally as the kākāriki karaka, is in the midst of a prolonged mating season due to a beech seed bonanza, Conservation Minister Eugenie Sage said in a statement on Wednesday.

Martin Shkreli — the former pharmaceutical CEO widely known as "Pharma Bro" — lost his bid to overturn a seven-year prison sentence for fraud Thursday. The U.S. Court of Appeals for the 2nd Circuit affirmed Shkreli's 2017 conviction.

Donald Trump took part in phone calls with his then-personal lawyer Michael Cohen as the attorney and other aides scrambled to arrange hush payments to a woman in 2016 to buy her silence about an alleged sexual relationship with Trump.

Those details come from hundreds of pages of court papers — warrant applications, affidavits and other related materials — made public on Thursday.

The best scene in Disney's incredibly photo-realistic remake of The Lion King features a computer-generated beetle rolling a ball of computer-generated dung across a computer-generated African landscape. It might sound mundane, but this particular ball of dung is carrying a tuft of fur from the runaway lion Simba, and its eventual discovery will renew hope that the rightful king of the savanna is alive and well. It's a funny, touching reminder that in the circle of life, every little creature and every lump of waste has an important role to play.
