Widespread condemnation after extraordinary breach of military intelligence

The breach was revealed in an article published on Monday by Jeffrey Goldberg, the editor of the Atlantic magazine, who discovered that he had been included in a Signal chat called “Houthi PC Small Group” and realising that 18 other members of the group included Trump cabinet members.

In his account, Goldberg said that he removed sensitive material from his account, including the identity of a senior CIA officer and current operational details.
