The co-chairman of a super PAC supporting Robert F. Kennedy, Jr.'s presidential campaign announced plans Tuesday to publish a tell-all memoir this summer by an Arkansas woman who shares a child with Hunter Biden, the youngest son of President Joe Biden. "Out of the Shadows: My Life Inside the Wild World of Hunter Biden" is written by Lunden Roberts, who gave birth to Hunter Biden's daughter in 2018. Biden — who has a long history of drug and alcohol addiction — wrote in his own 2021 memoir that he "had no recollection" of his encounter with Roberts. After initially contesting Roberts' paternity lawsuit, Biden in 2020 agreed to pay child support for his daughter with Roberts, after a DNA test confirmed the child was his.
