Charles Sauer, The Market Institute & Danielle Blevins, Freelance Reporter & Neil McCabe, Breitbart join Thom. In the wake of two more police killings of black men - Americans are once again calling for more scrutiny of law enforcement. In response - President Obama met today at the White House with Black Lives Matter activists and law enforcement officials. Meanwhile - North Carolina's Republican Governor Pat McRory is trying to make it harder for people in his state to hold police accountable. On Monday he signed a bill that would make it much more difficult for the public to get access to police body camera and dash cam footage. Police are public servants with immense power. Why are Republicans so committed to preventing them from undergoing any sort of scrutiny? They're exactly the type of people who we SHOULD be scrutinizing.

Tonight’s Rumble discusses the new details of the bizarre GOP platform, the latest Republican lies about social security and Medicare, and Justice Ginsberg’s comments on Donald Trump. Thom discusses the historic ice melting going on in the Arctic with Climatologist Jason Box and how bats can help end the Zika virus with biologist and TV host Eric Powers.

Patrick Sullivan, Center for Biological Diversity, is on with Thom. The Center for Biological Diversity has released a report detailing how the federal government allowed billions of gallons of waste oil to be dumped into the Gulf of Mexico between 2010 and 2014. So why are we finding out about it in 2016?

Bryan Pruitt, RedState & Jasmine Jefferson, Social Security Works & Alex Pfeiffer, The Daily Caller all join Thom. Republicans might still be holding Donald Trump at arm's length - but that isn't stopping them from agreeing on something every conservative can agree on - tax cuts for the rich. While the House Republican tax plan and Trump's tax plan have some differences - they share the same basic emphasis on making America's wealthiest pay less in taxes.
