Hunter Biden, the son of President Joe Biden, has often made headlines for his drug and alcohol addictions, but his relationship with his sister-in-law has also gotten him noticed. Hunter met his future wife Kathleen Biden (née Buhle) when he was working as a Jesuit volunteer at a church in Portland, Ore., according to The New Yorker. After just three months of dating, Kathleen became pregnant, and the two married in 1993. The couple had three children together, but by 2016, the couple had split and Kathleen had filed for divorce.

Meanwhile, after the tragic death of Hunter's brother, Beau Biden, from brain cancer in May 2015, Hunter and Beau's widow, Hallie, became close. The two texted "constantly," The New Yorker reported, and Hunter even started spending nights at Hallie's house in Delaware. "We were sharing a very specific grief," Hunter told The New Yorker. "I started to think of Hallie as the only person in my life who understood my loss." By 2017, Hunter and Hallie were officially a couple, dating for two years until they split in 2019, as reported by Page Six.
