AI Incident Database: MyPillow Defense Lawyers in Coomer v. Lindell Reportedly Sanctioned for Filing Court Document Allegedly Containing AI-Generated Legal Citations

In February 2025, lawyers Christopher I. Kachouroff and Jennifer T. DeMaster, representing Mike Lindell, reportedly used generative AI to draft a court brief that contained nearly 30 defective or fabricated citations. The error-filled filing violated federal court rules requiring factual and legal accuracy. The judge fined both lawyers $3,000 each, citing either the improper use of AI or gross carelessness as the cause of the misleading legal content.
