But it turns out that Michael Cohen, the lawyer they're hoping to use against former President Donald Trump in the criminal case in Manhattan, was caught using AI for citations that he gave his attorney that were then used in a motion filed with a federal judge.

This all came out because the judge in the case couldn't find three of the cases cited and ordered on Dec. 12 that Schwartz produce the cases and, if he couldn't, explain how non-existent cases got in his filings along with Cohen's role in them. The judge also asked Schwartz why he should not be sanctioned for made-up cases in his filing.
