Hunter Biden's tumultuous personal life became tabloid fodder during and after his father's time with the administration.
He sparked confusion when he, then 44 years old, enlisted in the Navy Reserves in 2012, less than two years before reports broke that the Reserve discharged him in 2014 after he tested positive for cocaine.
Hunter Biden eventually confirmed the news and said in a statement that it was "the honor of my life to serve in the U.S. Navy, and I deeply regret and am embarrassed that my actions led to my administrative discharge. I respect the Navy's decision. With the love and support of my family, I'm moving forward."
After tragedy struck the family through 46-year-old Beau Biden's death from cancer in 2015, Hunter Biden's personal life remained in the headlines.
After he divorced his first wife and the mother of his three daughters, Kathleen, the Biden family acknowledged he was dating Hallie Biden, Beau's widow.
Hunter Biden raised eyebrows with a candid New Yorker interview in which he said he spent the aftermath of his brother's death on a bender that included him buying crack from homeless people. He also said that he and Hallie Biden discovered they were "sharing a very specific grief" and spent a lot of time together in 2016 before they became a couple.
The couple apparently tried to keep the relationship secret, but the former vice president found out when Page Six called him for comment on a story on the relationship, after which he and Jill Biden issued a supportive statement.
"We are all lucky that Hunter and Hallie found each other as they were putting their lives together again after such sadness," the statement said. "They have mine and Jill's full and complete support and we are happy for them."
