spoke with the media. “There is no middle ground here,” Mr. Chenault told The Times. “You either are for more people voting, or you want to suppress the vote.”

“This was unprecedented,” Mr. Lewis said. “The African-American business community has never coalesced around a nonbusiness issue and issued a call to action to the broader corporate community.”

Mr. Bastian had been unable to sleep on Tuesday night after his call with Mr. Chenault, according to two people familiar with the matter. He had also been receiving a stream of emails about the law from Black Delta employees, who make up 21 percent of the company’s work force. Eventually, Mr. Bastian came to the conclusion that it was deeply problematic, the two people said.

accused Mr. Bastian of spreading “the same false attacks being repeated by partisan activists.” And Republicans in the Georgia house voted to strip Delta of a tax break, just as they did three years ago. “You don’t feed a dog that bites your hand,” said Mr. Ralston, the house speaker.

Senator Marco Rubio of Florida posted a video in which he called Delta and Coca-Cola “woke corporate hypocrites” and Mr. Trump joined the calls for a boycott of companies speaking out against the voting laws.

Companies that had taken a more cautious approach weren’t targeted the same way. UPS and Home Depot, big Atlanta employers, also faced early calls to oppose the Georgia law, but instead made unspecific commitments to voting rights.

declared their opposition to proposed voting legislation in that state. And on Friday, more than 170 companies signed a statement calling on elected officials around the country to refrain from enacting legislation that makes it harder for people to vote.

It was messy, but to many activists, it was progress. “Companies don’t exist in a vacuum,” said Stacey Abrams, who has worked for years to get out the Black vote in Georgia. “It’s going to take a national response by corporations to stop what happened in Georgia from happening in other states.”

Delta and Coca-Cola Reverse Course on Georgia Voting Law, Stating ‘Crystal Clear’ Opposition

In the memo, Mr. Bastian said it was only after the law was passed that he truly understood the degree to which it would impose restrictions on Black voters.

“After having time to now fully understand all that is in the bill, coupled with discussions with leaders and employees in the Black community, it’s evident that the bill includes provisions that will make it harder for many underrepresented voters, particularly Black voters, to exercise their constitutional right to elect their representatives,” he said. “That is wrong.”

Mr. Bastian went further, saying the new law was based on false pretenses.

“The entire rationale for this bill was based on a lie: that there was widespread voter fraud in Georgia in the 2020 elections,” he said. “This is simply not true. Unfortunately, that excuse is being used in states across the nation that are attempting to pass similar legislation to restrict voting rights.”

Several other companies also weighed in on the issue on Wednesday.

Larry Fink, the chief executive of BlackRock, issued a statement on LinkedIn saying the company was concerned about the wave of new restrictive voting laws. “BlackRock is concerned about efforts that could limit access to the ballot for anyone,” Mr. Fink said. “Voting should be easy and accessible for ALL eligible voters.”

Mark Mason, the chief financial officer of Citi, in a post on LinkedIn, called out the Georgia law as discriminatory.

“I am appalled by the recent voter suppression laws passed in the state of Georgia,” said Mr. Mason, who is Black. “I see it as a disgrace that our country’s efforts to keep Black Americans from engaging fully in our Constitutional right to vote continue to this day.”

Chuck Robbins, who is the chief executive of Cisco and grew up in Georgia, said on Twitter that “voting is a fundamental right in our democracy” and that “governments should be working to make it easier to vote, not harder.”

Black Executives Call on Corporations to Fight Restrictive Voting Laws

Dozens of the most prominent Black business leaders in America are banding together to call on companies to fight a wave of voting-rights bills being advanced by Republicans in at least 43 states. The campaign appears to be the first time that so many powerful Black executives have organized to directly call out their peers for failing to stand up for racial justice.

The effort, led by Kenneth Chenault, a former chief executive of American Express, and Kenneth Frazier, the chief executive of Merck, is a response to the swift passage of a Georgia law that they contend makes it harder for Black people to vote. As the debate about that bill raged in recent weeks, most major corporations — including those with headquarters in Atlanta — did not take a position on the legislation.

“There is no middle ground here,” Mr. Chenault said. “You either are for more people voting, or you want to suppress the vote.”

The executives did not criticize specific companies, but instead called on all of corporate America to publicly and directly oppose new laws that would restrict the rights of Black voters, and to use their clout, money and lobbyists to sway the debate with lawmakers.

almost no major companies spoke out against the legislation, which introduced stricter voter identification requirements for absentee balloting, limited drop boxes and expanded the legislature’s power over elections.

Big corporations based in Atlanta, including Delta Air Lines, Coca-Cola and Home Depot, offered general statements of support for voting rights, but none took a specific stance on the bills. The same was true for most of the executives who signed the new letter, including Mr. Frazier and Mr. Chenault.

Mr. Frazier said he had paid only peripheral attention to the matter before the Georgia law was passed on Thursday. “When the law passed, I started paying attention,” he said.

resignation led other chief executives to distance themselves from Mr. Trump, and the advisory groups disbanded.

“As African-American business executives, we don’t have the luxury of being bystanders to injustice,” Mr. Frazier said. “We don’t have the luxury of sitting on the sidelines when these kinds of injustices are happening all around us.”

a pledge that states their “clear opposition to harmful legislation aimed at restricting the access of L.G.B.T.Q. people in society.” Dozens of major companies, including AT&T, Facebook, Nike and Pfizer, signed on.

To Mr. Chenault, the contrast between the business community’s response to that issue and to voting restrictions that disproportionately harm Black voters was telling.

“You had 60 major companies — Amazon, Google, American Airlines — that signed on to the statement that states a very clear opposition to harmful legislation aimed at restricting the access of L.G.B.T.Q. people in society,” he said. “So, you know, it is bizarre that we don’t have companies standing up to this.”

“This is not new,” Mr. Chenault added. “When it comes to race, there’s differential treatment. That’s the reality.”

Activists are now calling for boycotts of Delta and Coca-Cola for their tepid engagement before the Georgia law was passed. And there are signs that other companies and sports leagues are becoming more engaged with the issue.

The head of the Major League Baseball Players Association said he “would look forward” to a discussion about moving the All-Star Game from Atlanta, where it is planned for July. And Jamie Dimon, the chief executive of JPMorgan Chase, released a statement on Tuesday affirming his company’s commitment to voting rights.

“Voting is fundamental to the health and future of our democracy,” he said. “We regularly encourage our employees to exercise their fundamental right to vote, and we stand against efforts that may prevent them from being able to do so.”

That language echoed statements made by many big companies before the Georgia law was passed. The executives who signed the letter are likely to seek more.

“People ask, ‘What can I do?’” Mr. Chenault said. “I’ll tell you what you can do. You can publicly oppose any discriminatory legislation and all measures designed to limit Americans’ ability to vote.”
