The 51-year-old reportedly sent racial slurs to corporate attorney George Mesires -- who is white -- in 2018 and 2019.
Daily Mail has obtained a copy of Hunter's hard drive after he left his computer at a repair shop, and what they have allegedly found is alarming.
In December 2018, Hunter reportedly asked his $845-per-hour attorney, "How much money do I owe you. Becaause [sic] n---- you better not be charging me Hennessy rates."
When Mesires wrote back, "That made me snarf my coffee," Hunter reportedly replied, "That's what im saying ni…," cutting off the word mind-slur.
In January 2019, Hunter was at it again, sending Mesires expletives when joking about a "big penis."
"I only love you because you're black," he allegedly wrote, later writing, "true dat n----."
In the same conversation, Joe Biden's son shut down his lawyer's philosophical banter with another profanity, even alluding to his late brother, Beau Biden.
"There are ideals of unconditional love that serve as proxies. I don't have many. You. God," Mesires joked.
"OMG n--- did you just a fictional character from the imagination of the collective frightened and my dead brothers unconditional love is what I should rely on and my kids aren't children George," Hunter replied.
A racial photo was also found stored on Hunter's laptop, including his father and former President Barack Obama.
In the meme, dated June 2017, Obama and Joe are seen embracing. It includes a joke of a mock conversation that never took place between the then-President and his Vice President.
"Obama: 'Gonna miss you, man,'" it read. "Joe: 'Can I say it? Just this once?'"
"Obama: '*sigh* go ahead,'" it continued. "Joe: 'You my n----, Barack.'"
The racial slurs aren't the only disturbing things that Daily Mail found on the copy of Hunter's hard drive.
Strings of emails, text messages, and x-rated photos allegedly showing Hunter with prostitutes were all exposed after the outlet got its hands on the copy.
