The Supreme Court on Thursday backed the National Rifle Association in a First Amendment ruling that will make it harder for state officials to put pressure on advocacy groups.

The decision means the NRA may sue a former New York official, Maria Vullo, who pressed banks as well as insurance companies to stop associating with the NRA after a 2018 mass shooting at a Parkland, Florida, according to CNN.

The ruling was unanimous and will reverse a lower court decision.
