Michael Horowitz, the Justice Department's inspector general, returned to Capitol Hill on Tuesday to take questions from lawmakers hoping to put their spin on the report his office released last week.

The nearly 600-page report is a comprehensive look at the Justice Department's handling of its investigation into Hillary Clinton's use of a private email server in 2016.

A record number of people have been forcibly displaced by war, violence and persecution, according to a new report from the U.N. High Commissioner for Refugees. 68.5 million people were forcibly displaced in 2017, setting a new record for the fifth straight year. 138,700 unaccompanied and separated children sought refuge and asylum in 2017, according to the agency.

Just outside tiny Sheffield, Iowa, a modern steel and glass office building has sprung up next to a cornfield. Behind it, there's a plant that employs almost 700 workers making Sukup brand steel grain bins. The factory provides an economic anchor for Sheffield, population 1,125.

Charles Sukup, the company's president, says that even though workers can be hard to come by, there are no plans to relocate.

"Our philosophy is you bloom where you're planted," Sukup says with a smile.

For most of her childhood, growing up in southeastern Pennsylvania, Kelly Zimmerman felt alone and anxious.

She despaired when her mother was depressed or working late shifts; when her parents fought nonstop; when her friends wanted to come over, and she felt too ashamed to let them see her home's buckling floor, the lack of running water.

Kelly tried to shut out those feelings, and when she was 18, a boyfriend offered her an opioid painkiller — Percocet.

Her anxiety dissolved, at least for a little while.

As the level of carbon dioxide in the air continues to rise because of human activity, scientists are trying to pin down how the plants we eat are being affected.

Mounting evidence suggests that many key plants lose nutritional value at higher CO2 levels, and scientists are running experiments all over the world to try to tease out the effects.

Some high school students think of applying to colleges as a full-time job. There are essays and tests, loads of financial documents to assemble and calculations to make. After all that comes a big decision — one of the biggest of their young lives.

North Korean leader Kim Jong Un arrived Tuesday in Beijing where he will spend two days, according to Chinese state media.

Xinhua announced his visit after reports of an Air Koryo flight, the North Korean state-run airline, was due to land in the Chinese capital. Kim's previous travels to China were not announced or publicized until after he had left, and the visit had concluded. This is Kim's second plane ride to China, according to NPR's Anthony Kuhn. Previously Kim had also traveled to China via armored-train.

Whenever you bring together dozens of different countries from around the globe, there's bound be some cross-cultural confusion. The World Cup is no exception.

And if you're Shin Tae-yong, coach of the South Korean national team, you figure out how to work that confusion to your advantage. In a press conference Sunday, Shin explained the unusual tactic he'd employed against scouts from the Swedish team: He'd had his team members swap jersey numbers for the warm-up games, in hopes that scouts wouldn't be able to tell the players apart.

President Trump Monday announced his intention to create a "space force" that would oversee the military's activities off-world.

"When it comes to defending America, it is not enough to merely have an American presence in space," Trump said at a meeting of the National Space Council, which oversees the nation's space policy. "We must have American dominance in space. So important."
