As the White House grapples with the fallout from the Signal chat leak scandal, a shocking report has emerged suggesting that Israel shared sensitive intelligence with the U.S. during recent operations against the Houthis in Yemen. 

According to The Wall Street Journal, Israel obtained classified information from a human source in Yemen. It relayed it to U.S. National Security Adviser Mike Waltz in an unclassified Signal chat with other officials from former President Donald Trump’s administration.

Shortly after the U.S. launched strikes in Yemen, Waltz messaged in the chat that a key target, a Houthi missile expert, was seen entering “his girlfriend’s” building, which was later destroyed in the attacks. A U.S. official familiar with the situation told WSJ that Israeli officials have privately expressed concerns to their American counterparts over Waltz’s messages becoming public.

Reports indicate that Israel assisted the U.S. in tracking Houthi militants in Yemen, underscoring the sensitive nature of some of the disclosures made in the group chat. This revelation comes at a time when nearly all former Trump officials have maintained that no classified information was shared on the Signal app, a publicly accessible, nongovernmental messaging platform.

The leaked chat displays US Vice President JD Vance asking National Security Adviser Mike Waltz for an update on the US strikes against the Houthis. Waltz replied that the attack had successfully targeted a top Houthi missile expert, “The first target—their top missile guy—we had positive ID of him walking into his girlfriend’s building, and it is now collapsed,” Waltz wrote, without revealing the source of the information. Waltz did not disclose the source of the information but stated in another message that the U.S. had "multiple positive IDs." The identity of the Israeli source in Yemen was also kept confidential in the conversations. However, Trump administration officials discussed how the U.S. had also gathered intelligence on the targets hit in the attack through surveillance drones operating over Yemen.

When WSJ questioned Waltz’s office whether Israel had provided the U.S. with information about the Houthi missile expert, National Security Council spokesman Brian Hughes responded, “No classified information was included in the thread.” He then reiterated the same statement, emphasising, "No classified information was included in the thread.”

Israel’s Prime Minister’s Office, the Israeli embassy in Washington, and several Trump officials refused to comment on the issue. As concerns grew, current and former U.S. officials warned that intelligence leaks could endanger foreign sources and discourage other nations from sharing sensitive information. In response, Trump officials stated that they have intensified their efforts recently to prevent the unauthorised disclosure of classified material.
