The defense secretary installed the encrypted-but-unclassified messaging app on a desktop computer in his Pentagon office to work around restrictions that prevent him from using personal devices to communicate with people outside headquarters.

Defense Secretary Pete Hegseth used his personal phone to send information about U.S. military operations in Yemen to a second Signal group chat — this time including his wife and his brother, two sources with knowledge of the matter confirmed to NBC News.

Sources said Defense Secretary Pete Hegseth shared information about a forthcoming U.S. attack on Houthi rebels in Yemen in a Signal message chat that included his wife, brother and personal lawyer.
