Investigative reporter Philip Shenon tells us about newly-declassified documents which shed light on Lee Harvey Oswald's trip to Mexico weeks before the assassination. He met with Cuban officials and may have boasted about planning to kill the President Kennedy. "It's remarkable to discover that the CIA itself describes what happened after the Kennedy assassination as being a cover up," Shenon says. Also, Aubrey Plaza joins 'Fresh Air' producer Ann Marie Baldonado to talk about 'Ingrid Goes West,' and her iconic role as April on 'Parks & Rec.'
