Subsidiaries of insurance giant AIG this week filed four lawsuits against companies accused of shipping “ghost gun” parts into New York, asking the court to declare that the insurers are not obligated to provide coverage for ghost gun-related lawsuits.

In all four cases, AIG subsidiary Granite State Insurance Company is represented by a Willkie Farr & Gallagher team led by partner Christopher St. Jeanos. In two of the suits, Willkie also represents AIG subsidiary and umbrella insurer National Union Fire Insurance Company.
