Bill Chappell, NPR

Bill Chappell is a writer and producer who currently works on The Two Way, NPR's flagship news portal. In the past, he has edited and coordinated digital features for Morning Edition and Fresh Air, in addition to editing the rundown of All Things Considered. He frequently contributes to other NPR blogs, such as All Tech Considered and The Salt.

Chappell's work at NPR has ranged from being the site's first full-time homepage editor to being the lead writer and editor on the London 2012 Olympics blog, The Torch. His assignments have included being the lead web producer for NPR's trip to Asia's Grand Trunk Road, as well as establishing the Peabody Award-winning StoryCorps on NPR.org.

In 2009, Chappell was a key editorial member of the small team that redesigned NPR's web site. One year later, the site won its first Peabody Award, along with the National Press Foundation's Excellence in Online Journalism award.

At NPR, Chappell has trained both digital and radio staff to use digital tools to tell compelling stories, in addition to "evangelizing" — promoting more collaboration between legacy and digital departments.

Prior to joining NPR in late 2003, Chappell worked on the Assignment Desk at CNN International, handling coverage in areas from the Middle East, Asia, Africa, Europe, and Latin America, and coordinating CNN's pool coverage out of Qatar during the Iraq war.

Chappell's work for CNN also included producing Web stories and editing digital video for SI.com, and editing and producing stories for CNN.com's features division.

Before joining CNN, Chappell wrote about movies, restaurants and music for alternative weeklies, in addition to his first job: editing the police blotter.

A holder of bachelor's degrees in English and History from the University of Georgia, he attended graduate school for English Literature at the University of South Carolina.

At a rally in Cincinnati on Thursday night, President-elect Donald Trump said he would select retired Marine Corps Gen. James Mattis to lead the Defense Department, filling a key role in the incoming administration. Mattis, 66, is famous for both his blunt talk and his engaging leadership in recent U.S. conflicts.

Its official name is the perigee-syzygy, meaning the moon is both full and closest to Earth. But many call it the supermoon, and Monday's version will be a "showstopper," NASA says. It's the nearest supermoon in almost 70 years — and we won't see another like it until 2034.

"When a full moon makes its closest pass to Earth in its orbit it appears up to 14 percent bigger and 30 percent brighter, making it a supermoon," NASA says.

Here are five things to help you enjoy this supermoon:

Following up on his letter that set off a firestorm of speculation just two weeks before U.S. voters head to the polls to choose a new president, FBI Director James Comey says the investigative team that analyzed a new trove of emails that were either to or from Hillary Clinton has finished its work — and that the review doesn't change the findings he put forth in July, when he said no charges will be pursued against Clinton.

Weeks after he left Rio's 2016 Summer Olympics under a cloud, U.S. swimming star Ryan Lochte is being punished for his behavior in Brazil, which ranged from an altercation at a gas station to making claims that he was robbed — claims that were later deemed to be false.

An earthquake struck northern Oklahoma early Saturday morning, rattling houses and waking residents in the region around Pawnee, about 74 miles north of Oklahoma City. Preliminary measurements show the quake had a magnitude of 5.6 — believed to be one of the strongest in state history.

The quake was felt in five states, according to the U.S. Geological Survey: Oklahoma, Kansas, Missouri, Arkansas and Texas. It struck just after 7 a.m. local time, at a depth of 6 kilometers (3.7 miles).

A day after police pulled two of Ryan Lochte's teammates off a U.S.-bound plane to discuss their claims of being robbed last weekend, we're seeing reports that the group was involved in an altercation that centered on a gas station's bathroom.

The police have scheduled a 2 p.m. ET news conference to discuss the case. But even as new details emerge, Rio 2016 spokesman Mario Andrada downplayed the case's significance at a briefing Thursday morning.

Gunnar Bentz and Jack Conger, American swimmers who were with Ryan Lochte last weekend when their group reportedly suffered a robbery, were pulled off their flight home from Rio's Summer Olympics on Wednesday by police seeking answers about the reported robbery.

It came down to penalty kicks — and after two of the U.S. women's soccer team players missed theirs, Hope Solo couldn't stop Sweden's shots in an elimination game in the quarter-finals of Rio's Summer Olympics.

Facing their old coach Pia Sundhage, the Americans were trying to improve on a draw with Colombia that marred an otherwise stellar opening round to the games in Brazil. But they couldn't capitalize on early chances against Sweden, and Sundhage's squad made them pay in the end.

The meeting was highly anticipated, and it didn't disappoint — particularly from Lilly King's point of view. One day after King spoke bluntly about rival Yuliya Efimova's doping offenses, she beat Efimova to win a gold medal in the women's 100-meter breaststroke at Rio's Summer Olympics.

"I'm proud to be competing clean and doing what is right," King said after the race. "But I need to respect the IOC's decision" — referring to the announcement over the weekend that Efimova would be allowed to compete.

Continuing its push into Web content and advertising, Verizon is buying Yahoo Inc. for about $4.83 billion in cash, the two companies confirmed Monday morning, ending a purchase process that began months ago.

The deal comes more than a year after Verizon paid $4.4 billion to acquire AOL, in a deal that was viewed as hinging on AOL's ad software and mobile video content.

Officials say a gunman shot and killed five police officers Thursday at a Dallas protest against police shootings of black men, in a bout of violence that didn't end until the suspected gunman was killed by police using a "bomb robot."

The suspect, who died in a parking garage, was named Micah Xavier Johnson, federal officials told NPR on Friday. Johnson was a military veteran who had served in Afghanistan, and told negotiators he was upset about police shootings and wanted to kill white police officers.
