Kittie Weston-Knauer, on the cusp of 70 years old, is the oldest female BMX bicycle racer in the U.S.

When she started competing in the late 1980s, she was often the only woman on the track. It was her son, Max Knauer, a champion BMX rider, who introduced her to the sport when he was 10.

Max, now 40, explains that he planted the racing seed after a frustrating day of his mom playing coach.

After a day of steady rain on Churchill Downs, it was Justify who managed to cross the finish line first in the mud.

Justify brought Hall of Fame jockey Mike Smith a second Derby victory. Smith previously won aboard Giacomo in 2005. Bob Baffert, the trainer of Triple Crown winner American Pharoah, seals his fifth Derby win.

Ten years ago, Tracia Kraemer wanted to celebrate her 40th birthday by trying something new.

So she mustered her courage and visited Indian Hills, a nudist park in Louisiana.

At the very least, she figured she'd return home with a good story. "I thought I'd go to Indian Hills, get naked, get dressed and drive off," she says.

But the people she met were so nice and welcoming, she says, that she decided to stay longer that day. "Soon after, I got a membership."

Two years after that first visit, she met her husband-to-be, Patrick Kraemer, at the park.

Charisse Spencer, 64, grew up in southeast Virginia during the 1960s civil rights movement.

Back then, the area of Portsmouth, Va., where her family lived — Cavalier Manor — was one of the largest black suburbs in the country.

"I could stand in my backyard and listen to Ku Klux Klan meetings," Charisse tells her son, Myles Spencer-Watson, in a StoryCorps conversation recorded in 2009. "And in my young mind, I'd imagine these ghostly demons in white sheets with their eyes being black holes and —"

A new exhibit that opens Monday at the United States Holocaust Memorial Museum aims to honor a founding mission.

Five years in the making, "Americans and the Holocaust" contextualizes attitudes in the U.S. during 1930s and '40s persecution and mass murder of Jews in Europe.

Twenty-five years ago, when the building opened, noted Holocaust survivor Elie Wiesel introduced the museum not as an answer to the horrors of genocide but to pose a glaring question: How could this happen?

Verne Troyer, best known for his comedic role as Mini-Me in two of the three Austin Powers movies, has died. He was 49.

Troyer starred alongside Mike Myers as the one-eighth-size clone and silent sidekick of villain Dr. Evil in 1999's Austin Powers: The Spy Who Shagged Me, and played Myers' tiny archenemy in the franchise's third installment, 2002's Austin Powers in Goldmember.

For much of Abby Gagliardo's childhood, her dad had been in and out of jail and prison. "People would ask me, they'd be like, 'Oh, where's your dad?' " Abby recalls in a StoryCorps conversation recorded last year, when she was 16.

She knew he was incarcerated, but she was never given a clear picture why. "I didn't understand any of it," she says.

Roxanne and Dennis Simmonds knew their son as fearless and strong from the day he was born.

"D.J. came out with shoulders of a linebacker," Roxanne says. "He was the first baby I saw that had muscles."

"He wasn't really afraid of anything," Dennis says.

At night, young D.J. would take the dog with him and circle the entire house, to "make sure there's nobody on the grounds," Dennis says, laughing. "I used to say, 'D.J. where you going? It's late.' He would say 'I'm doing a perimeter search, Dad.' "

StoryCorps' Military Voices Initiative records stories from members of the U.S. military and their families.

Good things come in small packages — it's a proverbial truth that, for one veteran, holds up even in the middle of war.

At 20 years old, Pfc. Roman Coley Davis found himself 7,000 miles from home. Born in Douglas, Ga., he'd joined the military after high school, and was now living in one of the most remote U.S. outposts in Afghanistan.

Brothers Russell, 28, and Remmick Wadsworth, 27, have autism. As kids, they had trouble with social interactions, so they often relied on each other for support during tough situations. Now, as the siblings navigate the working world, they're still looking out for each other.

Remmick remembers his first job, working with his older brother in a coffee shop. "You would always have my back, talking to customers for me, handle them for me while I make their drinks," he tells Russell during a StoryCorps conversation.

There's no crying in baseball. But for Kay Johnston, there's crying when you can't play.

In the spring of 1950, in upstate New York, 13-year-old Kay Johnston wanted nothing more than to play Little League baseball. But in those days, that was out of the question. Girls weren't encouraged to swing bats and throw balls.

As families around the country search for answers in the wake of school shootings in Parkland, Fla. and elsewhere, parents and children are having conversations that would've been almost unfathomable a generation ago.

"The pilot freed himself. The other five did not," FDNY Commissioner Daniel Nigro said in a news conference Sunday night.

Vince Cantu and Joe Galloway, both aged 76, have been friends since they met as third graders in the tiny town of Refugio, Texas.

After their high school graduation in 1959, Joe left town to become a journalist. Vince stuck around Refugio where he fronted a local band, until he was drafted into the Army in 1963. Naturally, the two lost track of each other over the years.

But the two reunited in a most unexpected place: in South Vietnam, where the U.S. was ratcheting up its involvement in the war. Joe and Vince recounted the moment during a StoryCorps interview.

Ashley Judd was one of the first women to publicly accuse Harvey Weinstein of sexual harassment.

When John Banvard, 100, met Gerard "Jerry" Nadeau, 72, in 1993, neither of them had been openly gay.

"When we met, we were sort of in the closet, and I'd never had a real relationship. Now, we've been together almost 25 years," Jerry tells John during a StoryCorps interview.

"What would it have been like if you didn't meet me?" Jerry asks John.

"I would have continued being lonely," John says. "I'd been absolutely lost."

A White House official confirms with NPR that Kathleen Hartnett White's controversial nomination to head the Council on Environmental Quality is being withdrawn.

Most people familiar with "face-swapping" know it as an innocuous social media feature. An algorithm captures a person's face and pastes it onto someone else's. The result is rarely seamless and often funny.

A favorite pastime for April Gibson and her teenage son, Gregory Bess, is simply talking to one another.

"I think I learn more from those conversations than school," says Gregory, who turned 17 on Thursday.

But during a recent StoryCorps conversation in St. Paul, Minn., April, 33, knew he wanted to talk about a subject the two hadn't really explored.

April invited her son to ask about what that time was like for her, as a young black mother. "Now you can ask me the hard question," April says.

"What did you feel like when I was born?" Gregory asks.

Rickey Jackson spent nearly four decades in prison for a crime he didn't commit.

In May of 1975, when a shopkeeper at a small Cleveland grocery store was slain during a robbery, Eddie Vernon, then 12 years old, served as the main witness in the case. Eddie — who, in fact, hadn't seen anything — says he was pressured into testifying by police.

In his annual New Year's address on Monday, North Korean leader Kim Jong Un warned the United States that his country's completed nuclear arsenal is now a button-push away.

"The U.S. should know that the button for nuclear weapons is on my table," he said, according to the Associated Press translation, in a speech carried by state television. "The entire area of the U.S. mainland is within our nuclear strike range. ... The United States can never start a war against me and our country."

Reuters reports:

Three officials at the Miss America Organization are stepping down after having been implicated in emails published by HuffPost on Thursday that contained crude language disparaging former pageant winners.

It was Christmas of 2001, and Thompson Williams' family was struggling financially. "That year we used all our money just before Christmas so that we could pay the bills and buy groceries — at least we'd have something to eat," he tells his son, Kiamichi-tet at StoryCorps.

Thompson was teaching students with special needs, and his wife was selling handmade Christmas ornaments. They lived in Edmond, Okla., with Kiamichi-tet, then 11, and their daughter AuNane, 14.

If you usually ring in the holiday with a freshly cut evergreen, your reality this Christmas could very well be a scrawny Charlie Brown tree instead — or you may wind up paying more for a lush Fraser fir.

This year, there is a tree shortage. Most growers blame the tightened supply on the Great Recession, says Valerie Bauerlein, who covered the story for The Wall Street Journal.

A central question of debate leading up to the Senate's passage of a sweeping tax overhaul plan asked which Americans need a boost. Economists say the Republicans' selling point for previous iterations of their legislation, that the plan is designed to benefit the middle class, has a shaky foundation — that the rich are the big winners.

For about six years, Lyon has been comforting patients in their final hours at St. Joseph Hospital in Orange, Calif.; for Wynn, it's been about nine years.

Transparent star Jeffrey Tambor has announced he may be leaving the hit Amazon series after two women accused him of sexual harassment.

Tambor continues to deny the allegations leveled this month by one of his co-stars on the show and by his former assistant. But the actor intimated his departure from the show, in a statement provided to NPR, due to a recent "politicized atmosphere" on the set.
