Elections officials across the country are preparing for a potentially bumpy election night. In this episode of “The Assignment,” Audie Cornish travels to Arizona to talk with one of those officials: Maricopa County Supervisor Bill Gates. He is a lifelong Republican who faced death threats and harassment from election deniers after he certified the results of the 2020 election. They discuss why election centers now look like forts – surrounded by barbed wire and shatterproof glass – all in the name of protecting election integrity. #electioninterference #politics #arizona #CNN #News
