Media organizations from across the country are urging a federal appeals court to reject an attempt to allow two teens to remain anonymous in a challenge to a new Florida gun law.

A brief filed last week on behalf of 21 organizations argued that allowing the teens to take part in the challenge as Jane Doe and John Doe would hinder public access to court proceedings. The National Rifle Association filed the challenge in March to a law that increased to 21 from 18 the minimum age to buy rifles and other long guns in Florida.
