Trump accuses Biden of ‘Big Man’ corruption in son’s overseas business dealings

"All of the emails, the horrible emails of the kind of money you were raking in… I think you owe an explanation to the American people," Trump referred to The New York Post's bombshell reporting last week on Hunter Biden's private emails. "I think you have to clean it up and talk to the American people," he added.

Then Biden claimed, "I have not taken a penny from any foreign source."

"I don't make money from China; you do. I don't make money from Ukraine; you do," Trump fired back. "I don't make money from Russia. You made $3.5 million, Joe. They even have a statement that we have to give 10 percent to the big man. You're the big man, I think. I don't know. Maybe you're not."

This comes after the 2017 email recovered from a hard drive formerly belonging to Biden's revealed a 10 percent set-aside for "the big guy" as part of a prospective deal involving the Chinese energy and finance conglomerate, CECF.

"10 held by H[unter] for the big guy," a Biden business partner wrote, quantifying the percent equity stake for the vice president under the Obama Administration at the time. Ex-Biden business associate turned-whistleblower Tony Bobulinski on Thursday corroborated the appearance of the Democratic ticket.

The two candidates squared off at the debate moderated by NBC's Kristen Welker on Thursday night at Belmont University in Nashville, Tenn., Each of the contender's microphone was muted while the other was allotted two minutes to answer at the beginning of each question. Then both mics were turned on for discussion. The new format was a reaction to the first face-off which saw repeated clashes between the dueling candidates.
