On this episode of “Sway,” Kara Swisher speaks to Gavin Newsom, a governor who is, by some measures, running a country. California is the world’s fifth-largest economy. And yesterday, the state joined the ranks of Britain, Denmark and Germany with an ambitious environmental order banning the sale of new gasoline-powered cars by 2035. Governor Newsom is making big moves, even in the midst of a pandemic and a wildfire crisis. He’s leading California as the state takes on the federal government — “We’d be in the hall of fame if this was a sporting event.” But how does the governor choose his battles? What goes through his mind when he sits opposite a president who once called climate change a hoax? And how will the governor salvage California’s environment, economy and morale after a brutal year?
