During the 2016 presidential campaign, NBC News correspondent Katy Tur felt the wrath of Donald Trump, who often disparaged her from the stage. She joins us to talk about what it was like to visit 40 states with the future president, which she writes about in “Unbelievable: My Front-Row Seat to the Craziest Campaign in American History” (Dey Street Books). She’ll take part in the Texas Tribune Festival in Austin this weekend.
