Priscilla Sims Brown, who leads the country’s largest union-owned bank, has also led an initiative to create a new merchant code for stand-alone gun stores, recently adopted by Visa, Mastercard, American Express and more. The code gives these companies a way to distinguish gun purchases from other sporting goods purchases — and flag concerning trends early, such as very large purchases of weapons and ammunition. Sims Brown discussed her efforts, how the bill came to pass and the potential impact it can have on combating gun violence with Andrew Ross Sorkin of The New York Times at the 2022 DealBook Conference.
