What was it like to be in the room for some of the most consequential foreign policy decisions of the Obama administration? Samantha Power started as an outsider, a war correspondent who became a voice of moral witness about the failings of the American government. That voice earned her a job in the cabinet of President Barack Obama, helping shape the foreign policy she was once a harsh critic of. Both as a member of the National Security Council, and later as Ambassador to the UN, she had the challenge of addressing her own criticisms within the confines of the job. Now, the Pulitzer Prize-winning author joins to give a rare glimpse into the experience of navigating those halls of power.
