For tonight's Conversations With Great Minds - we're going to take a closer look at the refugee crisis on our southern border, and the ongoing fight for comprehensive immigration reform. Since October of last year - almost 60,000 children - virtually all of them from Central American - have crossed without their parents and without documentation into the United States from Mexico. While at it's core it's a humanitiarian crisis - the surge in undocumented children has rapidly become a political crisis - bringing with it new questions about how we can fix our broken immigration system. Joining me now to discuss this crisis and what the response to these children says about America today and the future of immigration reform are three leading experts on the topic. Miriam Yeung is the Co-Chair of We Belong Together Campaign: Women for Common Sense Immigration Reform, and Executive Director of the National Asian Pacific American Women's Forum. Oscar Chacon is the Executive Director of the National Alliance of Latin American and Caribbean Communities and Mary Small is the Assistant Director for Policy at the Jesuit Refugee Service USA. It’s been more than a year since the Senate passed the bipartisan immigration bill reform - and John Boehner STILL hasn't brought that bill to the floor in the House. Is immigration reform dead or is there still time left to fix our broken system?

What drives resisters, whistleblowers and conscientious objectors? P1 Eyal Press, Beautiful Souls: Saying No, Breaking Ranks, and Heeding the Voice of Conscience in Dark Times joins Thom Hartmann. For Tonight's Conversations with Great Minds...we examine the question of what leads people to stand up - dissent - and show true moral courage during times of crisis - especially when there's great risk in doing so. What's drives these resisters - whistblowers - conscientious objectors - who throughout history have tried to warn entire societies of the risk of succumbing to authority and convention. It's a question tonight's guest sought ought to answer - by going all the way back to World War 2 and telling stories of those who've defied the Nazis. And later - stories of those who defied their own communities and governments and set their guns downs rather than fight a way they didn't believe in. And those who today are taking on Corporate America. Eyal Press is a journalist and author whose work has appeared in the New York Times Magazine, The Atlantic, and The Nation. He is a past recipient of the James Aronson Award for Social Justice Journalism. And he is the author of the book we'll explore tonight - Beautiful Souls: Saying No, Breaking Ranks, and Heeding the Voice of Conscience in Dark Times"
