Eunice Kennedy Shriver was the sister of President John F. Kennedy, and Senators Robert F. Kennedy and Ted Kennedy. Pulizer Prize-winning journalist Eileen McNamara worked at the Boston Globe for 30 years as a reporter and columnist. Her latest book is called “Eunice: The Kennedy Who Changed the World.” Eileen talks this hour with Interlochen Public Radio reporter Morgan Springer. Morgan asked Eileen why she gets angry when people lump all the Kennedy sisters together.
