The family of Ashli Babbitt, an Air Force veteran who was fatally shot in the U.S. Capitol on January 6, 2021, sued the U.S. government for $30 million on Friday claiming Babbitt was “ambushed” by a police officer.

Conservative watchdog group Judicial Watch filed the suit in California federal court on behalf of Babbitt’s estate and husband, Aaron, who is a resident of San Diego, alleging counts that included assault and battery, negligence, wrongful death and more.

The complaint particularly raises issues with the U.S. Capitol Police and then-Capitol Police Lt. Michael Byrd, the officer who shot Babbitt as she attempted to pass through a broken window of a barricaded lobby door, unarmed, during the breach that disrupted lawmakers certifying Joe Biden’s presidential victory.
