On Sunday, Colombia elected a new president, Ivan Duque, a conservative former senator who's pledged to rewrite a divisive peace treaty that ended the country's 50-year-old guerrilla war.

In the second and final round of elections, Duque won 54 percent of the vote, defeating former guerrilla fighter and onetime Bogota Mayor Gustavo Petro, 58, who captured about 42 percent in the runoff. Duque will succeed outgoing President Juan Manuel Santos.

That busboy was Juan Romero.

Kennedy was running for president and had just won the California Democratic primary when he was assassinated at the Los Angeles hotel.

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.

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?

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.

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with NPR that Kathleen Hartnett White's controversial nomination to head the Council on Environmental Quality is being withdrawn.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

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."

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.

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.
