Iowa atheist Justin Scott tells us about his experience interviewing political candidates in the Iowa caucuses about their views on the separation of state and church. After hearing Marco Rubio, Ted Cruz, Hillary Clinton and Bernie Sanders respond to Justin, we talk with Jane Donnelly by phone from Dublin, who just testified before the U.N. on behalf of Atheist Ireland and 'teachdontpreach.ie' about the problem of Catholic control of public schools in the Republic of Ireland.
