John Holdren was President Obama’s senior advisor on science and technology for eight years. In this conversation with producer Mike Osborne, Holdren discusses Obama’s passion for science and its role in all aspects of American life. He also tells us what it’s like to testify in front of Congress, which he calls “piñata day” (it sounds fun...until you realize he’s the piñata). Mike and John end by discussing the future of science and environmental policy under the Trump administration.
