He was a flamboyant, alpha-male billionaire who said things no career politician ever would — someone who promised to use his business savvy to reform the system and bring back jobs. Voters believed that his great wealth insulated him from corruption, because he couldn't be bought.

But his administration was marked by criminal investigations and crony capitalism.

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.

In the quest to help the poor, it's difficult to know whose needs are the greatest. Without clear data, it's tough to know who to help first.

The traditional way to look for the poorest of the poor is with household surveys. That's the primary source of data for policy decisions, but it has drawbacks.

A federal judge has overturned a military panel's decision to force a Marine out of service for using his Yahoo account to send an email that included classified information warning his fellow Marines about a corrupt Afghan official.

That warning was not taken seriously, as NPR's Quil Lawrence told our Newscast unit, and three Marines were killed shortly after. Later, "after some negative news coverage, the Marine Corps decided to force Jason Brezler out of the service for mishandling classified data."

Amazon says it is opening a new food and convenience store that doesn't have a checkout line.

Instead, the company envisions customers at the Amazon Go store picking up whatever they want off the shelves — then simply walking out with it. The items are automatically billed to their Amazon accounts.

Facebook, Microsoft, Twitter and YouTube say they are creating a database to keep track of terrorist recruitment videos and other terror-related images that have been removed from their services.

In a joint statement posted by Facebook on Monday, the company said:

The U.S. stock market is up more than 3 percent since Election Day four weeks ago.

One person who hasn't benefited: President-elect Donald Trump.

In a call with reporters, transition spokesman Jason Miller says Trump sold all of his holdings in the stock market over the summer. The move could remove some, but not all, potential conflicts of interest as the billionaire businessman takes office as president.

Even before the sale, stocks accounted for a tiny fraction of Trump's personal fortune. Most of his money is in real estate.

The Trump Organization has more interests in India — at least five — than anywhere else outside North America. With an ever-increasing taste for luxury, India offers the Trump brand a lucrative market, no matter who runs the company after President-elect Donald Trump separates from his global enterprises, as he's said he would do.

The U.S. Supreme Court has upheld a jury verdict finding that State Farm Fire and Casualty Co. defrauded the federal government after Hurricane Katrina hit the Gulf Coast in 2005.

In the years before the hurricane, State Farm issued both federal government-backed flood insurance policies and general homeowners policies. After the hurricane, the company ordered its claims adjusters to misclassify wind damage as flood damage to shift liability to the government and spare the insurance company's coffers.

The Lord's Resistance Army committed horrifying crimes against civilians for almost three decades, killing thousands in northern Uganda and beyond its borders.

Now, the first-ever trial of an LRA commander has opened at the International Criminal Court. Dominic Ongwen, who was kidnapped when he was a boy and forced to become a child soldier, "pleaded not guilty to 70 counts of war crimes and crimes against humanity — including murder and enslavement," as NPR's Ofeibea Quist-Arcton reports.
