What is it with our Presidents?  They all play golf. I think it has something to do with power. And friendship, too. Gary Ginsberg wrote a book called “First Friends.” It’s about nine U.S. Presidents and the people closest to them like Abe Lincoln and Joshua Speed. They slept in the same bed for four years. Vernon Jordan stayed loyal to Bill Clinton even as impeachment loomed. And then there’s Donald Trump the loner. He didn’t have a best friend. We talk about the long arm of history and friends in high places. “Now What?” is produced with the help of Steve Zimmer, Fei Lu and Alex Wolfe. Audio production is by Nick Ciavatta.
