We hear from a former State Department senior adviser who says North Korea’s recent change in tone over next month’s planned summit with President Trump isn’t “impulsive,” but rather “part of a longer-term strategy.” Also, New York magazine published a story this week about the dynamics of the relationship between Fox News host Sean Hannity and President Trump — a connection based mainly on late-night phone calls. We talk with reporter Olivia Nuzzi, who wrote the story. And the new book “West Like Lightning” tells the story of the Pony Express, which for a brief period in 1860 and 1861 reduced the time it took to carry messages from Missouri to California to around 10 days. That and more, in hour one of Here & Now’s May 16, 2018 full broadcast.
