'The Atlantic' Editor-in-Chief, Jeffrey Goldberg, discusses the “Signalgate” scandal with Anne Applebaum at Tulane's BookFest

Just days after news broke that The Atlantic's Editor-in-Chief, Jeffrey Goldberg, was inadvertently included in a Signal group chat discussing classified U.S. military operations, Goldberg took center stage at the opening night of The New Orleans Book Festival at Tulane University.

Lines wrapped around McAlister Auditorium Thursday evening. Shortly before the program began at 5 p.m., security told Tulane officials the building was at capacity, leaving many outside waiting to get in.

Goldberg's story, which was first published in The Atlantic, sent shockwaves through the U.S. this week after it was revealed that he was mistakenly added to a secure Signal group chat by White House officials, where airstrikes in Yemen were reportedly discussed.

National Security Advisor Michael Waltz has taken responsibility, calling it an internal error. President Donald Trump addressed the incident earlier today, stating that the aide would be “dealt with appropriately.”

Goldberg was joined on the panel by other top Atlantic journalists, including Anne Applebaum, Adam Serwer, Elaina Plott Calabro, and McKay Coppins. The event, billed as “The Atlantic’s live exploration of our journalism,” is drawing heightened attention in light of the ongoing fallout in Washington.

Goldberg was supposed to moderate Thursday's event, but due to his 'seismic reporting', which is being called 'Signal-gate,' the panel began with Applebaum asking Goldberg questions.

During the discussion, Goldberg said he contacted security agencies to ask if any of the information was too sensitive to publish.

The CIA asked him to withhold certain sensitive information included in the chat. Goldberg said the editor decided to comply because they did not want to put service members at risk.

However, the White House told him the information was not sensitive but asked it not to be published, Goldberg said.
