Viewers are probably familiar with CNN correspondent Jim Acosta. Over the last two years, with the Trump administration escalating its anti-press rhetoric, Acosta has often been the target of its attacks. He's written a new book, "Enemy of the People," and he talks about it with host Robin Young. Also, construction is underway on a new international airport near the ancient Inca ruins of Machu Picchu. Historians and conservationists worry the project will disturb important archaeological sites in the area of Chinchero, which is part of Peru's "Sacred Valley."
