High-level Trump officials used the digital messaging app Signal to communicate sensitive details about an impending military strike against Houthi terrorists in Yemen earlier this month, sparking interest in the app's use in communicating confidential information.

The encrypted chat app beloved by Elon Musk and foreign dissidents has been embraced by federal government workers, DOGE and military planners.

Top Trump administration officials accidentally shared highly sensitive attack plans on Iranian-backed militants in Yemen with a journalist on the messaging app Signal. Signal is a free, encrypted messaging service that is not approved by the government for classified communications.
