On today’s show: Philip Shenon shares his secret history of the Kennedy assassination—and tries to answer questions about President Kennedy’s death that people are still asking 50 years later. Lupita Nyong’o talks about her breakout role as Patsey in the film “12 Years a Slave.” Victoria Loustalot describes making peace with her father’s memory by taking the trip he had promised to take her on before he developed AIDS and died.
