As the Trump team scrambles to contain the fallout over the signal scandal, former Republican Senator and U.S. Defense Secretary under President Barack Obama, Chuck Hagel, talked to Christiane about the far-reaching consequences of this blunder. Then she speaks with best-selling author Michael Lewis and satirist W. Kamau Bell, about their new book called, "Who is Government? The Untold Story of Public Service.," which profiles the civil servants being targeted by the new administration in their federal government cuts. Plus, Ivan Watson reports on the hundreds of people trapped inside “scam compounds” in the warlord-controlled border region of Myanmar, the nexus of a billion-dollar scam industry, where hundreds of thousands of trafficked people have been working as modern slaves, conning victims around the world out of their savings. Then, as “The Sound of Music" turns 60, Christiane revisits her conversation with Julie Andrews about her legendary career and some behind-the-scenes moments. Plus, as the administration's foreign aid cut halt the critical cleanup of Agent Orange and other diplomatic efforts in Vietnam, Christiane's 60 Minutes report highlights the devastating impact of the toxic chemical on the local population and U.S. vets alike, and the reason for the much-needed U.S. assistance to this day.
