President Biden repeatedly has insisted he never has spoken with his son Hunter about the family's business deals with Chinese communist-run firms, Russian and Ukrainian oligarchs, and others.

But now, along with other accumulating evidence, comes the unearthing of a voicemail, with the president's voice, asking Hunter to call him back regarding his deal with CEFC Energy China, DailyMail.com reported Monday.

That was the multi-million-dollar deal in which the "big guy" – identified by a Hunter Biden business partner as Joe Biden – was to get 10% equity in a joint venture with CEFC, according to an email from Hunter Biden's abandoned laptop. The company is an arm of Communist Party Chairman Xi Jinping's chief global domination venture, the "Belt and Road Initiative." One of the witnesses before a Delaware grand jury investigating Hunter Biden's business dealings, according to a source, has been asked: Who is the Big Guy?"

In the Dec. 12, 2018, voicemail, Joe Biden references a New York Times story about Hunter's dealings with CEFC. The paper reported CEFC chairman Ye Jianming had been arrested in China. And Ye's top lieutenant Patrick Ho had been convicted in the U.S. for bribery.

"Hey pal, it's Dad. It's 8:15 on Wednesday night. If you get a chance just give me a call. Nothing urgent. I just wanted to talk to you," Joe Biden said.

"I thought the article released online, it's going to be printed tomorrow in the Times, was good. I think you're clear. And anyway if you get a chance give me a call, I love you."
