Hunter Biden and the president's brother James "profited from a $5 million wire from a company connected to CEFC (the Chinese Energy firm) in August of 2017."
The email, with the subject line, "Expectations," outlines a "provisional agreement" for "equity" in a deal with a Chinese energy company.
Two of Hunter's former business partners, including Tony Bobulinski, who received the email, have told CBS News that "10 held by H for the big guy?" is shorthand for 10% held by Hunter for his father.
