(Washington, DC) -- Hunter Biden talks about his addiction to crack cocaine in an upcoming memoir. In excerpts published in the New York Times, the President's son gives graphic details of his struggles with drugs and alcohol. He writes that in the past five years alone, his 20-year marriage had dissolved, guns have been put in his face and he was living in motels because of his addictions. Hunter says he's now clean, and credits his new wife Melissa Cohen for his sobriety. Hunter Biden's memoir "Beautiful Things" comes out Tuesday.
