Presidential Debate 2020: Trump's 'Big Surprise' Brings Hunter Biden's Ex-Associate As Guest

President Donald Trump on Thursday night brought Hunter Biden's former associate as a guest to the final presidential debate in hopes that the Trump campaign could use a "big surprise" against Joe Biden.

Tony Bobulinski, in the audience at the debate, held a surprise conference, nearly two hours before the start of the event, and accused the Democrataic challenger of "lying" over claims that he did not have any knowledge of his son's business affairs, The New York Post reported.

"I have heard Joe Biden say he has never discussed his dealings with Hunter. That is false. I have firsthand knowledge about this because I directly dealt with the Biden family, including Joe Biden," Bobulinski said.

Bobulinski also showed three phones that allegedly contained evidence of business dealings with the Biden family spanning 2015 to 2018.

His appearance comes after the Post published a piece that includes screenshots of incriminating emails between Hunter Biden and a Ukrainian business executive. The emails were taken from a laptop that allegedly belonged to Hunter.

In a separate story, the Post also published more emails that indicated Hunter had accepted money from a Chinese company. Bobulinski claimed the evidence showed a connection between the Bidens and China.

According to a statement from Washington Republican Sen. Ron Johnson, the Senate and the FBI have requested documents and electronic devices related to Bobulinski's affairs with the Biden family. He is expected to appear in an informal interview with a Senate panel on Friday, Newsweek reported.

"As part of the committees' efforts to validate the authenticity of recently publicly released emails involving the Biden family's international financial entanglements, we sent letters to five individuals identified in the emails," the statement read.

"So far, the committees have received a response only from Mr. Tony Bobulinski, who appears to be willing to fully cooperate with our investigation," the statement continued.

Trump's latest debate stunt resembles one he made in 2016, when he brought former President Bill Clinton accusers Kathleen Willey, Juanita Broaddrick, and Paula Jones as his guests. The president had live-streamed a panel with the three women who had accused Clinton of sexual harassment two hours before the debate began, CNN reported.

The president also invited Kathy Shelton in 2016. She was the victim of a rape whose perpetrator was defended by former vice presidential candidate Hillary Clinton in court. The rapist was given a lesser charge and only 10 months in prison.
