Naomi Klein: The Politics of the Green New Deal, plus Dahlia Lithwick on Trump's 'Emergency'

Naomi Klein says the Green New Deal needs to follow the example of the New Deal of the 1930s, when nothing would have happened without “massive pressure from social movements” that “changed the calculus of what was possible.” Naomi is a contributing editor at The Nation and author of several number one bestsellers, including “This Changes Everything.” Plus Dahlia Lithwick talks about the national challenge to Trump’s “national emergency”—the constitutional issues, the political issues, and the dangers of treating as normal his rambling, fact-free, egomaniacal performance in the Rose Garden announcing his “emergency.” Dahlia writes about the courts and the law for Slate and hosts the podcast ‘Amicus.’
