On Saturday afternoon, as hundreds of thousands of people joined the March for Our Lives around the nation, I was on the phone with Michael Corbat, chief executive of Citigroup.
Mr. Corbat had taken the remarkable step on Thursday of authorizing a new set of rules to restrict gun sales by Citi’s clients, the first time a Wall Street bank had used its position to influence the gun control debate.
Five weeks earlier, a gunman’s attack at a high school in Parkland, Fla., had left 17 dead. Soon afterward, I wrote a column challenging the business world to “effectively set new rules for the sales of guns in America,” given Washington’s intransigence.
