Hunter Biden is suing Garrett Ziegler, a former aide to former President Donald Trump, over his part in publishing emails, embarrassing images, videos and recordings belonging to Biden.

Filed on Wednesday in California, the lawsuit accuses Ziegler and 10 unnamed defendants of violating the state’s computer fraud laws by “accessing, tampering with, manipulating, altering, copying and damaging computer data” as part of a “sustained, unhinged and obsessed campaign” against the Biden family.

“While Defendant Ziegler is entitled to his extremist and counterfactual opinions, he has no right to engage in illegal activities to advance his right-wing agenda,” the lawsuit reads.

The laptop, now infamous, has been a key part of investigations alleging corruption on the part of the Biden family. The lawsuit also identifies an encrypted iPhone that was allegedly hacked by Ziegler and others to access data.

Ziegler is a vocal critic of the Biden family and previously worked in Trump’s administration as an economic aide to former advisor Peter Navarro, who was convicted of contempt of Congress last week.

Legal experts say the lawsuit could send a signal to others.

“This is a fascinating offensive move by Hunter Biden, and may very well be undertaken to be a shot across the bow for those who are thinking of joining on the bandwagon in allegedly slandering him,” wrote former federal prosecutor Andrew Weissman in a post on X, the social media platform formerly known as Twitter.
