The revelations of a second Signal chat raise more questions about Hegseth's use of an unclassified messaging system to share highly sensitive security details and come at a particularly delicate moment for him, with senior officials ousted from the Pentagon last week as part of an internal leak investigation.
In the second chat, Hegseth shared details of the attack similar to those revealed last month by The Atlantic magazine after its editor-in-chief, Jeffrey Goldberg, was included in a separate chat on the Signal app by mistake. The chat included details of the schedule of the air strikes, the source said.
