In a new video, former New York City Mayor Rudy Giuliani unleashed on former Vice President Joe Biden, calling him "the prince of darkness" for using his son Hunter Biden to conduct overseas business dealings.

"Joe Biden, the guy who used his son, a drug addict, to be his bag man. Why do you think he lost his teeth at 40 years old?" Giuliani unleashed.

Rudy continued by commenting on the type of people who Hunter Biden was doing business with.

"What do you think happens to a drug addict, dad, when you put him in with people like that?" he questioned. "He becomes a much worse drug addict. He becomes a degenerate drug addict."

"You couldn’t find some bum in Washington to do this for you? You had to use your son and ruin his life?" Giuliani continued. "And you want to be President of our country?  My goodness, you should check in to the local federal prison and start doing your time.  That’s where you belong, not in the White House."

"You used your family to pick up your bribes, hide your bribes, live the life of a billionaire," he added. "And by the way, I don’t think you failed in all those negotiations just because you’re stupid. I think you failed in those negotiations because you sold out the United States of America. That’s what I think you did. And you’re ready to do it again if we didn’t catch you."

WATCH:

The situation surrounding Hunter Biden seems to be getting worse. According to new documents, federal investigators obtained a Foreign Intelligence Surveillance Act warrant against Hunter Biden Chinese business associate Chi Ping Patrick Ho.

The documents were obtained by the Daily Caller News Foundation and show that the warrant was filed in February of 2018.

The Daily Caller reports:

Ho was charged on Dec. 18, 2017 with conspiracy to violate the Foreign Corrupt Practices Act and money laundering related to CEFC China Energy contracts in Uganda and Chad. Ho had been an executive at the multi-billion dollar Chinese energy company prior to his arrest.

Hunter Biden was part of a business consortium that sought a partnership with CEFC in May 2017. A Senate report released last month said that an affiliate of CEFC wired $5 million to Biden’s law firm from August 2017 through August 2018.

In addition to his partnership with CEFC, Hunter Biden also represented Ho during his legal battle.

According to a report from The New Yorker last year, CEFC’s chairman, Ye Jianming, raised concerns with Biden in summer 2017 about a possible investigation into Ho.

Biden agreed to represent Ho and to find out the extent of the investigation, according to The New Yorker report.

The New York Times reported in December 2018 that Ho’s first call following his arrest the year before was to James Biden, the brother of the former vice president.

The Senate report also said that a shell company affiliated with CEFC called Hudson West III wired $1 million to Biden’s law firm, Owasco, on March 22, 2018.

The payment was designated for “Dr Patrick Ho Chi Ping Representation,” the report says.

The Republican senators who released the report asserted that Biden’s relationship with CEFC posed counterintelligence concerns, in part due to Ye’s links to the People’s Liberation Army and the Chinese Communist Party.

The court filings in Ho’s case suggest that federal investigators had counterintelligence concerns about Ho.

According to the court documents, investigators obtained a FISA warrant which then allowed them to conduct physical surveillance of Ho's property.

“The United States intends to offer into evidence, or otherwise use or disclose in any proceedings in the above-captioned matter, information obtained or derived from electronic surveillance and physical search conducted pursuant to the Foreign Intelligence Surveillance Act,” prosecutors said.

The Daily Caller continues:

Ho’s lawyers tried to block evidence obtained through the FISA process from being used at Ho’s trial, according to one filing submitted in his case.

Prosecutors in the Southern District of New York, where the case was tried, responded in a court filing of their own defending the use of evidence from the FISA in Ho’s case. They did not disclose the basis for obtaining the FISA warrant or say when it was granted.

The court filing also says that the evidence derived from the FISAs was classified.

Ho was convicted in March 2019 and sentenced to three years in prison.

On Tuesday, the National Pulse website published an audio recording purportedly from Hunter Biden’s laptop in which he referred to Ho as a “spy chief.”

“I have another New York Times reporter calling about my representation of Patrick Ho – the fucking spy chief of China who started the company that my partner, who is worth $323 billion, founded and is now missing,” Biden is heard saying on the audio recording, according to The National Pulse.

Hunter Biden indicated in text messages early on in his dealings with CEFC that he suspected his work with the firm might require him to register with the Justice Department under the Foreign Agents Registration Act (FARA).

He wrote to a business associate on May 1, 2017 that they should form a U.S.-based partnership in order to avoid scrutiny under FARA or the Foreign Corrupt Practices Act (FCPA), the law that Ho was eventually charged under.

“We don’t want to have to register as foreign agents under the FCPA which is much more expansive than people who should know choose not to know,” Hunter Biden wrote to his then-business partner Tony Bobulinski on May 1, 2017, according to a message obtained by the DCNF.

The FISA process came under intense scrutiny during the investigation of the Trump campaign’s ties to Russia because the FBI was found to have misled the FISC regarding evidence against Carter Page.

The Justice Department invalidated two of the four FISA warrants granted against Page because the FBI submitted false information to the FISC.

Unlike Ho, Page was never accused of criminal wrongdoing. One piece of evidence that the FBI withheld from the FISC was that Page had a previous relationship with the CIA.

The Foreign Intelligence Surveillance Court grants surveillance authorization to the FBI and Justice Department in cases in which there is probable cause to suspect the subject of the warrant is working covertly for a foreign government.
