Ex-Trump lawyer Michael Cohen says he unwittingly sent AI-generated fake legal cases to his attorney
NEW YORK — Michael Cohen, Donald Trump’s onetime personal lawyer and fixer, says he unwittingly passed along to his attorney bogus artificial intelligence-generated legal case citations he got online before they were submitted to a judge.
Cohen made the admission in a court filing unsealed Friday in Manhattan federal court after a judge earlier this month asked a lawyer to explain how court rulings that do not exist were cited in a motion submitted on Cohen’s behalf. Judge Jesse Furman had also asked what role, if any, Cohen played in drafting the motion.

The AI-generated cases were cited as part of written arguments attorney David M. Schwartz made to try to bring an early end to Cohen’s court supervision after he served more than a year behind bars.
Cohen had pleaded guilty in 2018 to tax evasion, campaign finance charges and lying to Congress, saying Trump directed him to arrange the payment of hush money to a porn actor and to a former Playboy model to fend off damage to his 2016 presidential bid.
Cohen, who was disbarred five years ago, said in a declaration submitted to the judge on Thursday that he found the citations by doing research through Google Bard and was unaware that the service could generate nonexistent cases. He said he uses the internet for research because he no longer has access to formal legal-research sources.
“As a non-lawyer, I have not kept up with emerging trends (and related risks) in legal technology and did not realize that Google Bard was a generative text service that, like Chat-GPT, could show citations and descriptions that looked real but actually were not,” Cohen said. “Instead, I understood it to be a super-charged search engine and had repeatedly used it in other contexts to (successfully) find accurate information online.”
Google rolled out Bard earlier this year as an answer to ChatGPT, which Microsoft has been integrating into its Bing search engine. The tools can quickly generate text based off prompts from a user, but have a tendency to make things up, also known as “hallucinations.”
Cohen blamed Schwartz, his lawyer and longtime friend, for failing to check the validity of his citations before submitting them to the judge, though he asked that the judge dispense mercy toward Schwartz, calling his failure to check the citations an “honest mistake” and “a product of inadvertence, not any intent to deceive.”
In a declaration filed with the court, Schwartz said he thought drafts of the papers to be submitted to the judge to dissolve Cohen’s probation early were reviewed by E. Danya Perry, a former federal prosecutor now in private practice who also represents Cohen.
