Former Vice President Joe Biden's son Hunter Biden’s alleged drug use and infidelity was, in part, what led to the end of his marriage.
That's according to his estranged wife Kathleen, to whom he is still married ... while dating his late brother Beau's widow Hallie Biden.
Kathleen filed a new motion in D.C. Superior Court on February 23, just one week before Hunter and Hallie's relationship went public.
Hallie and Hunter confirmed they are dating in a statement.
Not happy about that for a variety of reasons, Kathleen claims that her husband has behaved in a manner unbecoming of him - financially.
Hunter, she says, has “created financial concerns for the family by spending extravagantly on his own interests” during their separation.
Those interests include “drugs, alcohol, prostitutes, strip clubs, and gifts for women with whom he has sexual relations,” she alleges.
She also claims that the family (the couple share three children) has no funds to pay their bills because of Hunter’s continued spending.
Kathleen further claims in court papers that Hunter instructed his office to reduce the monthly funds she received by nearly $10,000.
That was in October, allegedly, but even after he had curtailed his payments to her, he “secretly continued to spend lavishly."
All the while, "complaining to Ms. Biden, through counsel, about the financial issues of the family and Ms. Biden’s spending.”
Kathleen goes on to claim in documents that Hunter had $122,179 of their marital income transferred into his personal bank account.
The money was gone, she says, in “less than two months.”
She claims that the family has maxed out its credit cards, owes numerous outstanding bills, and has incurred a tax debt of at least $313,970.
She is requesting Hunter be provided only a $5,000 a month allowance, and that she be given $20,000 a month, according to reports.
Hunter Biden's attorney responded, “Hunter and Kathleen have been separated for some time and are in the process of finalizing a divorce."
"Hunter loves and admires Kathleen as a person, a mother, and a friend. He hopes their privacy can be respected at this time.”
The couple married in July 1993 and separated not long after Beau Biden (above) died in 2015 following a battle with brain cancer.
This week, Hunter announced that he and Beau's widow, Hallie, have become involved in a romantic relationship of their own.
“Hallie and I are incredibly lucky to have found the love and support we have for each other in such a difficult time," he said.
"That’s been obvious to the people who love us most. We’ve been so lucky to have family and friends who have supported us every step of the way.”
The former Vice President and wife Dr. Jill Biden also said in a statement that they are aware of the relationship and support it.
“We are all lucky that Hunter and Hallie found each other as they were putting their lives together again after such sadness."
"They have mine and Jill’s full and complete support and we are happy for them,” Joe and Jill said of their son and daughter-in-law.
Beau Biden died of brain cancer in May 2015, a fact that is believed to have led to the decision of Joe Biden not running for President.
Hunter and Kathleen split in October of that year, five months after Beau died. They have three daughters, Naomi, Finnegan and Maisy.
Beau, the former attorney general of Delaware, and Hallie have two children, a daughter Natalie and, confusingly, a son Hunter.
