The White House's internal investigation into how Atlantic editor-in-chief Jeffrey Goldberg became part of a Signal group chat with Trump administration officials found that an iPhone auto-suggestion played a key role.
It was revealed that after Goldberg emailed the White House for comment on a story, a Trump spokesperson, Brian Hughes, texted the contents of Goldberg's email to National Security Adviser Mike Waltz.
As a result, Waltz's iPhone saved Goldberg's phone number under Hughes' name as a contact suggestion update.
When Waltz tried to add Hughes to the Signal chat, he accidentally added Goldberg instead.
