Pete Buttigieg talks about the impeachment trial and how his campaign is gearing up for the crucial Iowa caucuses in an exclusive sit down interview with Inside Edition’s Deborah Norville. "If this president is innocent, why are they working so hard to suppress witnesses?" Buttigieg said. "Shouldn't witnesses and evidence help show that the president's innocent?" Buttigieg says playing his guitar helps him relax during his campaign. “When I’m playing music I don’t think as much,” he said.
