Hunter Biden had a controversial affair with his brother Beau's grieving widow Hallie, while exchanging raunchy texts, 'partying', and even renting a house with her sister, DailyMail.com can exclusively reveal. Hallie Biden's older sister, Elizabeth Secundy, who was recently separated from her husband of 15 years, referred to Hunter as her 'prince' and told him she loved him, in a series of text messages dating back to 2016. The pair's relationship was revealed in files and emails recovered from Hunter's laptop - the contents of which became public last year after it was abandoned at a Delaware computer shop.
