A federal appeals court next month will hear arguments in the National Rifle Association’s constitutional challenge to a Florida law that prevents people under age 21 from purchasing rifles and other long guns.

Gun safety groups are joining together to endorse President Joe Biden in 2024, as the president continues to push for stricter gun laws as a major part of his political platform that was all but unthinkable for Democrats even a few years ago.

The National Rifle Association says its longtime lobbyist in Florida, Marion Hammer, will retire but remain an adviser to the organization.

A federal judge has upheld Florida’s law prohibiting the sale of firearms to anyone under the age of 21.

A group called Ban Assault Weapons Now sponsored the proposed constitutional amendment, inspired by the mass shooting at a Parkland high school that left 17 people dead. While the ballot summary purports to exempt registered assault weapons lawfully possessed prior to the Initiatives effective date, the Initiative does not categorically exempt the assault weapon, only the current owners possession of that assault weapon. The ballot summary is therefore affirmatively misleading, the court wrote in its opinion. But since the petitions used the language the court says is invalid, the group cant simply tweak the ballot summary. Attorney General Ashley Moody opposed the ballot initiative, as did the National Rifle Association, which hired a legal team to fight it.

TALLAHASSEE, Fla. The National Rifle Association and Florida officials will avoid mediation in a lawsuit challenging a 2018 state law that prevents people under age 21 from purchasing firearms, under an order issued this week by a federal judge. The law raised the age from 18 to 21 to purchase long guns, such as rifles and shotguns. Accordingly, the issues involved in this case are not amenable to mediation. Mediation would not be a productive exercise, nor would it be a worthwhile use of the parties, or the courts, resources, the lawyers wrote. In Mondays order granting the request, Walker wrote this court finds good cause has been shown why the mediation requirement should be waived.

Justin Sullivan/Getty Images(CNN) - Walgreens is asking customers to no longer openly carry guns into its stores in states where open carry is legal, the company announced Thursday. It joins fellow retailers Walmart and Kroger, which announced similar policies the day before. Watts said Moms Demand had been pushing Walmart and Kroger to stop allowing open carry since 2014, and Walgreens since 2015. Watts said that in addition to keeping employees and customers safer, asking customers not to openly carry guns in their stores puts these retailers on a new side of the gun debate. "Prohibiting open carry sends a very strong cultural signal that companies are siding with the safety of families," Watts said.
