The American Civil Liberties Union, no stranger to taking on unpopular clients, nevertheless raised eyebrows and drew criticism this weekend when it confirmed that it would be representing the National Rifle Association in a case before the U.S. Supreme Court. 

In NRA v. Vullo, the controversial gun-rights organization is asking the Supreme Court to revive a lawsuit claiming that the former head of New York’s Department of Financial Services embarked on an unconstitutional pressure campaign to get banks and insurance companies to cut ties with the NRA after the deadly mass shooting at Marjory Stoneman Douglas High School in Parkland, Florida.
