In the revealing tell-all book, Hunter Biden is very forthcoming about his relationship with his late brother's widow. The president's son says he began spending a lot of time with Hallie Biden and the children and spent many nights at their home and even took the kids to school in the morning.
Biden claims it wasn't until after he left Grace Grove rehab center in Sedona, Arizona, that he began a relationship with Hallie.
"Feeling physically and mentally purged, I phoned Hallie and asked if she would come to Arizona to pick me up. I wanted her to accompany me on the trip back," Hunter wrote. " I didn’t trust myself to make it home without backsliding -- without taking a detour into the pit I fell into on my way there."
"She flew out the next day," he continued. "I was at my lowest, she was at her neediest, and we clung to each other with abandon. We talked at length about how much we had come to rely on each other, how our health and well-being seemed dependent on the love we’d grown to share."
Hunter said there was no doubt the unseen force in the middle of it all was Beau and they'd come to think they could keep his memory alive by being together and "that by loving each other we somehow could love him back into existence."
"By the time we returned to Delaware at the end of the week, we were no longer just two people bound by shared grief. We were a couple," he said. "It was an affair built on need, hope, frailty, and doom."
Hunter went on to say the pair tried to keep their relationship a secret but it didn't last long as his estranged wife Kathleen found texts exchanged between them on an iPad. He and his wife had separated since Beau's death but not formally divorced.
He says that was when everything blew up, "That gave her the gift of justification: I was the sicko sleeping with my brother's wife."
Hunter soon came to the realization that his relationship with Hallie was a "giant miscalculation on both our parts, errors in judgement born of a uniquely tragic time." Just three months after moving in with Hallie and her children, he moved out.
In the book, he also addresses the shocking details of his decades-long struggle with drug addiction, as well as his time on the board of Burisma.
The book is scheduled to be released on April 6.
