Guest host Mike Papantonio is in for Thom Hartmann tonight and discusses the battle over the TPP with Democracy For America’s Jim Dean, whether surveillance under the Patriot Act will be extended with Truthdig’s Robert Scheer, whether a GOP governor could become our next president with Salon’s Paul Rosenberg, and whether Freddie Gray was given a “rough ride” with Aaron Watson.

Congressman Alan Grayson (D-FL, 9th district) joins Thom. As Congress prepares to consider a bill giving him fast track powers - President Obama is now pushing the TPP hard - calling it a bridge to the future. But is it a bridge to the future, or just another grab-bag for the world's multinational corporations?

Caroline Fredrickson, American Constitution Society for Law and Policy / Demos / Under the Bus: How Working Women Are Being Run Over joins Thom. More than 50 years after the passage of the Equal Pay Act - the wage gap is still a fact of life in America. Why is that? And what does it have to do with our troubled history of slavery and racial discrimination?

Thom discusses fast-track and the TPP with Rep. Alan Grayson and whether European officials are pushing for regime change in Greece with Mark Weisbrot of the Center for Economic and Policy Research. In tonight’s special Thursday edition of “Conversations with Great Minds” Thom talks with Constitution Society for Law and Policy’s Caroline Fredrickson, author of the new book “Under the Bus: How Working Women Are Being Run Over.”
