Sam Sacks, The District Sentinel, joins Thom. A new rule will make bosses report to the federal government for hiring outside firms to help disrupt union drives. And the Republican party is really unhappy about it.

Thom discusses the approved and proposed mergers in the cable and health insurance industries with radio host and activist Richard Eskow, GOP union busting with The District Sentinel’s Sam Sacks, and what millennials need to know about social security with Social Security Works’ Jasmine Jefferson. And in tonight’s Conversations with Great Minds Thom discusses the presidential race and how to break through power with consumer advocate, activist, and author Ralph Nader.

Alexey Yaroshevsky, RT America joins Thom. It's now been thirty years since the worst nuclear disaster in history. On April 26, 1986 - the reactor of the Chernobyl Nuclear Power Plant in the city of Pripyat, Ukraine exploded - sending a massive cloud of radioactive material into the atmosphere. Radiation continued to flowed out of the destroyed plant for 10 straight days - spreading toxic materials for over 77,000 square miles. 31 people died in the ensuing cleanup - and many thousands of other deaths have been connected to the disaster - as have countless cases of cancer. To this day - the area around the Chernobyl plan is surrounded by a 19 square mile exclusion zone - and it will take 20,000 years before it's safe again for humans to live there. What happened in Chernobyl remains a potent warning about the dangers of atomic power - that the worst really can happen. So - thirty years on - how much closer are we to grappling with that reality?

Horace Cooper, Conservative Commentator/Attorney & Neil Sroka, Democracy for America & Crystal Wright, Con Job/RT America all join Thom. A campaign in Colorado is looking to start the nation's first state-based "single payer" health insurance system that will provide universal healthcare coverage and replace insurance premiums with higher taxes. Business interests in Colorado though - like The Council of Insurance Agents and Brokers and The Colorado Association of Commerce and industry - are building a coalition to block the measure.
