When Donald Trump won the presidential election, he made a pledge to every citizen: that he would be president for all Americans. In the weeks before Trump's inauguration, we're going to hear about some of the communities that make up this nation, from the people who know them best, in our series Finding America.

The No. 48 bus runs through the Central District of Seattle.

We're near the end of an eight-year chapter in American history, one that began with the election of Barack Obama in 2008. It's ending as a new president takes power after another election that forced Americans to confront questions of race.

The path of the Ohio River snakes southwest out of Pittsburgh and forms the border between Ohio and West Virginia. Here, the foothills of the Appalachian Mountains rise along its banks, and beneath that Appalachian soil lie the natural resources that have sustained the valley's economy: coal — and now, natural gas.

To people far away, who consume goods made with energy fueled by the Ohio Valley, coal and gas may be harmful agents of global warming.

But to people in Ohio coal country, a good life on the ground is paid for by what's underneath it.

It's been nearly a year since Mayor Karen Weaver declared a state of emergency in Flint, Mich.

Before she became mayor, the city switched its water supply to the Flint River in a cost-cutting measure. The water wasn't properly treated, which caused corrosion in old pipes — leaching lead and other toxins into the city's tap water. People were afraid to drink or even bathe in the water.

Since then, a lot has happened.

Thirty years ago, a new face debuted on daytime television: Oprah Winfrey.

The new podcast, "Making Oprah," produced by member station WBEZ, chronicles Oprah's rise to stardom. Journalist Jenn White tells Oprah's story from her early days on her first talk show, AM Chicago, through to the biggest, most outrageous moments when 40 million people a week were watching her national show.

Fake news played a bigger role in this past presidential election than ever seen before. And sometimes it has had serious repercussions for real people and businesses.

That's what happened to a pizzeria in Washington, D.C., recently, when an armed man claiming to be "self-investigating" a fake news story entered the restaurant and fired off several rounds.

We like to think our brains can make rational decisions — but maybe they can't.

The way risks are presented can change the way we respond, says best-selling author Michael Lewis. In his new book, The Undoing Project, Lewis tells the story of Daniel Kahneman and Amos Tversky, two Israeli psychologists who made some surprising discoveries about the way people make decisions. Along the way, they also founded an entire branch of psychology called behavioral economics.

Seventy-five years after the Japanese attack on Pearl Harbor, some Americans have never stopped believing that President Franklin Roosevelt let it happen in order to draw the U.S. into World War II.

"It's ridiculous," says Rob Citino, a senior researcher at the National World War II Museum in New Orleans. "But it's evergreen. It never stops. My students, over 30 years — there'd always be someone in class [who'd say], 'Roosevelt knew all about it.'"
