Inside Hallie Biden's toxic relationship with Hunter and Joe

Hallie Biden's history with the Biden family is a toxic one: Beginning a tawdry affair with her dead husband Beau's brother, getting sucked into the vortex of Hunter's addiction to crack cocaine and having her trips to rehab visits paid for by the president, DailyMail.com can reveal. Now, Hallie, 50, is set to testify for the prosecution in Hunter's Delaware gun crimes trial on Thursday, detailing how they frequently abused drugs in the late 2010s. DailyMail.com can exclusively reveal material from Hunter's abandoned laptop that lays bare Hallie's own struggles with drug addiction, her involvement with Hunter's firm, Rosemont Seneca, and her twisted relationship with the president's only surviving son.

Hallie Olivere, who grew up in Delaware and whose mother was friends with Joe, joined the Biden clan in 2002 when she married Beau. He became state attorney general in 2007. Though Hunter's prolific drug addiction and downward spiral into binges with [adult workers] has been well-publicized, messages and videos from his laptop reveal that Hallie was also in the throes of addiction during their twisted relationship. It got so bad that even Hunter tried to persuade her to stop.

In a January 2019 phone call Hunter recorded with Hallie she begged him to come and take drugs with her, telling him: 'I'm going to use regardless, but I would rather use with you.' Hunter videoed himself having another phone call with Hallie in which she asked him to get drugs for her. 'I want to help you from f***ing up, Hal. You're gonna lose your children,' Hunter said. 'Just help me get it, please,' she replied. She added that she planned to ask a friend for cocaine. 'Hallie, there is no way in hell you think that Lisa doesn't know that you've been in and out of rehab, all the struggles you're going through, and is going to get you cocaine,' he said. 'I don't know. I still think she would,' Hallie replied. 'You don't think she would call your sister who would call your mom who would call my dad? Absolutely 100% she would,' Hunter said.

Hunter wrote in messages that Hallie had been to rehab four times, costing over $100,000 – some of it paid for by Joe Biden. In December 2018 Hunter wrote a ranting text to Hallie referring to '$57,000 I paid for you at Passages ($5,700 per day) or the $45,000 Dad paid at Caron (4500 per day you stayed).' Both Passages and Caron are rehab centers. Her testimony on Thursday at Hunter's trial in Wilmington, Delaware, is set to bolster the prosecution against her former lover.

She is expected to detail how Hunter was a drug abuser during the period he bought a gun in October 2018 , when he claimed on a federal form that he was not an addict. It is a felony to lie on such forms. Hunter's lawyers have tried to cast doubt on the authenticity of text messages Hunter sent to Hallie two days after he bought the gun, in which he told her that he was 'smoking crack'. But Hallie is also expected to confirm on the stand Thursday that the texts were real.

Hallie is testifying as part of an immunity deal, protecting her from prosecution for her own crack use provided she tells the truth. She will also be protected when she admits on the stand how she found Hunter's gun in his truck and dumped it in a supermarket trash can opposite a Wilmington high school on October 23, 2018 – setting off a police investigation that ultimately led to Hunter. Hallie and Hunter's addictions created rifts in the family, with Hunter's texts full of accusations and drama about their arguments that enveloped the whole clan.

Venomous texts sent by Ashley Biden – Hunter's half-sister, who herself spent time in rehab – blame Hallie for Hunter's drug spiral and accuse her of picking up crack from a dealer in Delaware, even suggesting that she was being monitored by law enforcement. 'Don't think anyone wants that on front page of news journal. ''Attorney Generals widow buying crack and meth'' – something has to give,' Ashley wrote referring to Wilmington's daily newspaper. 'Enough is enough. My brother wouldn't stand for this s***.' 'I don't have proof of this but I would be careful as s*** because what was implied to me was whomever is giving them s*** is being monitored by law enforcement.' Texts also show Joe was aware of Hallie's addiction.

In July 2018 Hunter sent a recording to his father of himself talking on the phone to Hallie, arguing over how she planned to buy and cook crack cocaine. Joe responded: 'Got your text. Can't say I'm surprised. Going to bed I'll call you tomorrow morning. Love you. Be strong. Love Dad.' The financial relationship between Hunter and his sister-in-law-cum-lover also grew from around 2016. Amid Hunter's split with his first wife Kathleen Buhle that year, she emailed him furiously about expensive gifts he was buying Hallie.

On July 18, 2016 Kathleen emailed Hunter about Hallie, writing: 'You cheated on me. You continued to cheat on me while I worked with [their therapists] to get you help. 'Not only did you cheat on me, Viagra and Cialis, you actually bought her expensive gifts.' Photos on Hunter's laptop include Hallie posing in a fur coat he appears to have bought her. Documents show Hunter also hired Hallie at his consultancy firm Rosemont Seneca in 2018.

His secretary, Katie Dodge, sent Hunter a document showing Hallie listed on the firm's health insurance plan, and when he asked for a payroll review in December 2018 she texted that Hallie had been on the books since March that year. Hunter even divulged to his lover and brother's widow some of the most concerning allegations surrounding his multi-million-dollar deal with Chinese oil giant CEFC – which bank statements show Hallie profited from. On December 14, 2018, Hunter texted her a desperate screed, confessing that his client was Beijing's 'chief of intelligence'. 'I find myself (because I've chosen to alienate all my friends and family and employees and you and the kids and my kids etc..) very alone in dealing with rebuilding an income that can support an enormous alimony and my kids costs and myself,' he wrote.

'..[D]ealing with the aftermath of the abduction and likely assassination (that's what NYT's suspects) of my business partner the richest man in the world, the arrest and conviction of my client the chief of intelligence of the people's republic of China by the U.S. government, the retaliation of the Chinese in the ouster and arrest of U.S. suspected CIA operatives inside China, my suspected involvement in brokering a deal with Vladimir Putin directly for the largest sale of oil gas assets inside Russia to China, a tax bill that Eric [Schwerin, his Rosemont business partner] left hanging over my business and… Dads running for president.'
