Trump defended Defense Secretary Pete Hegseth, following reports of another Signal chat that included his wife and brother. 'Pete's doing a great job,' he said.

The news comes about a month after the editor-in-chief of The Atlantic was mistakenly added to a separate Signal chat with national security leaders.

Three officials told NBC News that Secretary of Defense Pete Hegseth shared information with his wife and brother that came from a top general's secure messages. Hegseth has denied sharing classified information on Signal.
