Today on Morning Joe: Mike Barnicle, Tom Brokaw and Nancy Palmer remember Nancy’s husband, TV legend John Palmer and discuss his memoir, “Newscatcher,” which debuted recently. Mike says, “There was an element to John, I don’t know whether it’s generational or whether it’s from his roots…he was a nice man, a generous man, willing to spend time with younger reporters — imparting his wisdom to them. Do you sense that that is missing at all today in our business?”
