Today, hosts Cat Brooks and Mitch Jeserich interview investigative journalist Eileen Markey, author of "A Radical Faith: The Assassination of Sister Maura." Markey's book centers around the 1980 murder of four American women by the U.S.-trained military of El Salvador, which set off a decade of debate over Cold War policy in Latin America.
