Joe Biden's family members are telling a New York tabloid that the widow of Beau Biden is in a relationship with Beau's married brother. The "New York Post" says Hallie Biden began her relationship with Hunter Biden after her husband, Beau, died of brain cancer in 2015. Hunter Biden is Beau's brother and has three children with his estranged wife, Kathleen. Hunter made headlines in 2013 when he was discharged from the Navy Reserve after testing positive for cocaine. The 47-year-old lawyer told the "Post," "Hallie and I are incredibly lucky to have found the love and support we have for each other in such a difficult time." Joe Biden is giving his approval. The former Vice President told the "Post," "They have mine and Jill's full and complete support and we are happy for them."
