GOP Senator says Hunter Biden’s lawyers are standing in the way of investigation

"We have only gotten response from Hunter and Devin’s attorney not to cooperate. No one else has even responded to us," Johnson said.

After the interview, Johnson tweeted out his frustration, pointing a finger at the elder Biden.

"Let's face it," Johnson said, "Joe Biden has not been honest with the American public. He had to know about Hunter Biden’s financial entanglements and particularly China. He shook hands with Jonathan Li, one of his business partners. Now we've found out that Hunter Biden wrote an email to his landlord asking for keys for Joe Biden, James Biden, Gongwen Dong? The signage was supposed to reflect Hudson West, which was the CEFC USA subsidiary. Now CEFC, that’s that Chinese company. It was taken over by the state in 2018; its chairman just 'disappeared,' Ye Jianming. This is an individual that had ties to the Communist Party of China as well as the People’s Liberation Army."

"So we are finding more and more of how involved not only Hunter Biden was," Johnson said, "but also James as well as Joe Biden, and he has not been truthful with the American public, and it’s about time that the press started asking questions. As I said before this election, this is not going away. This is a big mess. It's going to be a bigger mess if it becomes a Biden presidency, and that looks like the way we’re headed."

Since the US Attorney's Office launched an investigation on Hunter Biden's taxes, the president-elect's son has said he would be willing to cooperate with any investigation. Biden put out a statement last week saying that he takes the matter very seriously.

"I learned yesterday for the first time that the US Attorney's Office in Delaware advised my legal counsel, also yesterday, that they are investigating my tax affairs," Biden said.

"I take this matter very seriously but I am confident that a professional and objective review of these matters will demonstrate that I handled my affairs legally and appropriately, including the benefit of professional tax advisors."

So far, neither Joe Biden nor Hunter Biden has added anything on the ongoing investigation. When asked about the U.S. Attorney's Office probing of Hunter Biden’s taxes, the President Elect told reporters he would stand by his son.

"I'm proud of my son," Joe Biden said.
