Former President Obama urges responsible social-media use by "all of us in leadership," in an interview with Prince Harry that was broadcast on today's BBC Radio 4's "Today." The interview, which Obama said was his first as former president, was recorded in Toronto in September during the Invictus Games. Prince Harry was one of several of the program's guest editors over Christmas.

Obama, who doesn't mention Trump: "One of the dangers of the Internet is that people can have entirely different realities. They can be cocooned in information that reinforces their current biases."
