Giuliani said his results go well beyond influence peddling with foreign powers and alleged payments he has accused former Vice President Joe Biden of engaging in.
"This is a really very, very sensitive one," Giuliani told, referring to a text conversation he declares took place between Hunter and his father Joe Biden.
"There's a sexual depravity to this that's disgusting," he said.
Giuliani alleges the text message and photos involve an unnamed 14-year-old girl.
The former New York City mayor provided a photo image of the text message which he said shows Hunter Biden's message to his father, discussing claims he had behaved inappropriately around a younger female.
The purported message stated:
"She she told my therapist that I was sexually inappropriate with [redacted] when she says that I face time naked with her and the reason I can't have her out to see me is because I'll walk around naked ... When she was pressed she said that [redacted] never said anything like that but the bottom line is that I create and caused a very unsafe environment for the kids"
"If it stopped there I would let it go"
Giuliani also argued there were several pictures of underage girls on the Hunter Biden hard drive.
So disturbing was the content, Giuliani said he and former New York Police Commissioner Bernie Kerik met Monday with Delaware State Police and turned over their evidence.
"We're very uncomfortable with this," Giuliani said. "We're very uncomfortable with the fact that these underage girls were not protected.
"If you were to look at the photographs on this hard drive and didn't report it to the police — well, if you were a law enforcement officer, you'd be guilty of a felony.
"If you were just a normal citizen, you'd be a horrible human being," the former U.S. attorney for the Southern District of New York said.
"There are numerous pictures here of girls that are being, I mean, they shouldn't be there. That I can tell you. If the Delaware State Police don't do anything about this, it would be really a tragic thing."
Giuliani, President Donald Trump's lawyer, called the Hunter Biden laptop discoveries "probably the worst scandal I have ever seen."
He added, "And there's a depravity to it that's horrendous, which is why I reported to the Delaware police."
He claims Joe Biden had an interest in using his son Hunter as a "bag man" for influence peddling and bribes from foreign powers that overrode his interest in acting to protect his son and others.
