Just seven days after the Signal chat scandal erupted, the White House announced that it doesn’t want to talk about it anymore. In fact, it was Monday when press secretary Karoline Leavitt said that, as far as she and her colleagues are concerned, “this case has been closed.”

President Donald Trump told reporters on Wednesday that he "always thought" national security advisor Mike Waltz was responsible for the Signal chat scandal.

Iran said it saw another reason for skepticism over recent diplomatic overtures by the United States following the release of a Signal chat that included sensitive information on air strikes on the Houthi militant group in Yemen. U.S. officials have accused Iran of supporting the Islamist group.
