Rep. Max Miller, the embattled Ohio congressman who is facing an uphill battle to keep his seat following abuse allegations, was sued by his ex-wife on behalf of their 2-year-old daughter Wednesday over the accidental release of a nude image of the child.

The civil rights lawsuit, filed by Emily Moreno in Ohio federal court, claims that Miller “recklessly published” the image when he and his attorney, Aaron Minc, shared a link to a Dropbox folder that included the sensitive image earlier this month.

CNN has reached out to a representative of Miller and Minc for comment on the new lawsuit.

Miller had released the materials following a livestream on August 2 in an effort to defend himself against his ex-wife’s claims of domestic abuse, linking to the files on his X account, where he has nearly 60,000 followers. The photo was taken in the context of an inquiry into an injury the 2-year-old had suffered. Minc took responsibility for the image being included in the link the following day.

The image was publicly available for about a day before being removed.
