The Atlantic's editor-in-chief, Jeffrey Goldberg, has released more messages from the Signal chat group for senior Trump administration officials that he was accidentally added to, in which discussions about an upcoming strike on the Houthis took place.

President Trump's national security adviser has denied knowing the editor of The Atlantic after accidentally adding him to a sensitive group chat.

Journalist Jeffrey Goldberg is accusing Mike Waltz of lying about talking with him — ridiculing on Sunday the claim that his phone number was mysteriously “sucked into” the national security adviser’s cellphone before being included in a Signal group chat about Yemen airstrikes.
