Tuesday on Fox News Channel’s “The Ingraham Angle,” Government Accountability Institute president and Breitbart News senior contributor-at-large Peter Schweizer, author of “Secret Empires,” said there was reason for the U.S. Senate to call on former Vice President Joe Biden’s son Hunter Biden to testify about his dealings with Ukraine and China.

The elder Biden is a candidate for the 2020 Democratic Party presidential nomination.

“[T]he mystifying thing, Laura, is that you and I both know and I think most Americans know if the name here was Don Jr. and not Hunter Biden that the media would be all over this,” Schweizer said. “And it is surprising to me the lack of curiosity that a sitting vice president’s son is striking three major deals with the Chinese government while he is steering U.S. policy towards China, the deal with Ukraine. All of this stuff. If this was Don Jr, you know he would be sitting in front of Congress. And he should if he did that. Hunter Biden needs to do that. The Senate needs to ask him to testify.”
