The National Security Council said it was looking into how a journalist’s number was added to the chain in the Signal group chat.
Trump administration officials, including the defense secretary, shared war plans for military strikes in Yemen via the Signal app in a group chat that included a journalist from The Atlantic. The National Security Council is investigating how the journalist was added to the chat. Trump claimed to be unaware of the incident. Use of Signal also continued in the Biden administration for sensitive matters but less sensitive than Trump.
