Biden sued Giuliani and several limited liability companies he owns, along with Giuliani’s attorney Robert Costello and 10 unnamed individuals, accusing them of violating the Computer Fraud and Abuse Act, California Computer Data Access and Fraud Act and rules against unfair business practices.

The lawsuit takes issue with Giuliani and Costello’s possession of Biden’s “laptop”—which the lawsuit notes is not an actual laptop, but rather “an ‘external drive’ that Defendants were told contained hundreds of gigabytes of Plaintiff’s personal data”—which the defendants have allegedly illegally hacked and tampered with, making “further alterations and damage to the data.”

After being given a copy of Biden’s digital data by John Paul Mac Isaac, who worked at the computer store where Biden dropped off his laptop and never picked it up, Giuliani and Costello allegedly “repeatedly accessed Plaintiff’s account to gain access to the drive; and they proceeded to tamper with, manipulate, alter, damage and create ‘bootable copies’ of Plaintiff’s data over a period of many months, if not years,” the lawsuit says.

Giuliani repeatedly “bragged” about copying and sharing Biden’s data and loading it onto other devices in public podcasts and interviews, the lawsuit alleges, and invited other people to access and manipulate the data.

The lawsuit says Biden never authorized or consented to Giuliani or anyone else accessing his data, and the defendants “gained unlawful access to Plaintiff’s data by circumventing technical or code-based barriers that were designed and intended to prevent such access.”

Giuliani’s spokesperson Ted Goodman and Costello have not yet responded to requests for comment.
