Eldadah corrected her father.

"No, Daddy, the idea is that the car is actually going to do the tawaf," she said. "It's a drive-through."

Dr. William Strudwick was finishing a shift at Washington, D.C.'s Howard University Hospital when his wife, Maria, texted. Their 19-year old son, Cole, wanted to join a protest five days after the killing of George Floyd.

It was 9 p.m. After dark, Strudwick weighed, he couldn't predict how protesters would act — or how police would treat his son. He wrote back one word to his wife: "No."

"When I came home, he was not there, and so I called him," Strudwick said. "And we had the conversation about him returning immediately."

Last October, Ayanda erected a prefabricated shack made of corrugated zinc sheets nailed to a wooden frame on a hillside in South African wine country outside the town of Stellenbosch.

"We're moving forward with additional sanctions on Iran," the president said, speaking to reporters Saturday outside the White House. "Some of them are in place.
