Calls for Defense Secretary Pete Hegseth and national security adviser Michael Waltz to resign are increasing after The Atlantic magazine revealed both officials had discussed precise information about the U.S. bombing of Yemen on a group Signal chat that accidentally included Atlantic editor Jeffrey Goldberg. Hegseth posted detailed information on the timing and weapons used in the March 15 bombing. Waltz revealed the U.S. killed one target by bombing the building where the target’s girlfriend lived.

The White House has downplayed the growing scandal, describing it as a hoax while claiming no classified information was shared — a claim widely disputed by former intelligence officials. Several Republican lawmakers are now calling for an investigation.

During a House hearing Wednesday, Democratic Congressmember Raja Krishnamoorthi called for Hegseth to resign.

Rep. Raja Krishnamoorthi: “This text message is clearly classified information. Secretary Hegseth has disclosed military plans, as well as classified information. He needs to resign immediately. He needs to resign immediately, and a full investigation needs to be undertaken with regard to whether other similar Signal chats are occurring in this administration.”
