In “Battle for the Soul: Inside the Democrats’ Campaigns to Defeat Trump,” published on Wednesday, author Edward-Isaac Dovere describes how Sanders would request that the temperature in his room be kept at 60 degrees “even if that required having a staffer sit in the room with an open window in the winter to make sure it cooled enough or calling management in to override the system,” according to an excerpt cited by Fox News.
Dovere, a former Politico journalist who now writes for The Atlantic, reportedly said his research for the book included more than 400 interviews conducted over a four-year period.
