The FBI, meanwhile, says it’s investigating death threats sent to Bowe Bergdahl’s father, Bob. The first of the threats were received last week when the town of Hailey, Idaho, canceled a rally celebrating the younger Bergdahl’s release. Bob Bergdahl has been the target of right-wing criticism after he learned to speak Pashto and grew out his beard in a bid to reach out to his son’s captors.
