For two weeks, Delta Air Lines and Coca-Cola had been under pressure from activists and Black executives who wanted the companies to publicly oppose a new law in Georgia that makes it harder for people to vote. On Wednesday, six days after the law was passed, both companies stated their “crystal clear” opposition to it. Now Republicans are mad at the companies for speaking out. Hours after the companies made their statements, Gov. Brian Kemp, a Republican, took aim at Ed Bastian, the chief executive of Delta, accusing him of spreading “the same false attacks being repeated by partisan activists.” And Republicans in the Georgia state legislature floated the idea of increasing taxes on Delta as retribution.
