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

February 25, 2025

In February 2025, lawyers Christopher I. Kachouroff and Jennifer T. DeMaster, representing Mike Lindell, were reportedly sanctioned for using generative AI to draft a court brief containing nearly 30 defective or fabricated citations. This filing, which violated federal court rules demanding factual and legal accuracy, led to a $3,000 fine for each lawyer due to the judge's suspicion of either improper AI usage or gross negligence in the creation of misleading legal content. The incident serves as a stark reminder of the importance of trustworthy AI, safe and secure AI practices, and AI governance.
