White House, Shaken by Signal Scandal, Says Case Is Closed

The Trump administration sought to put the scandal over its use of the Signal messaging app behind it on Monday, calling it case closed, even as the breach provoked bipartisan criticism and opened up divisions inside the White House.

Press Secretary Karoline Leavitt told reporters at the White House that the administration maintained confidence in National Security Advisor Mike Waltz, who has faced criticism for apparently adding the editor of The Atlantic magazine to a private thread describing an imminent bombing campaign in Yemen.

Leavitt said that steps have been taken to prevent a repeat of the incident, though she did not elaborate.

"As the president has made it very clear, Mike Waltz continues to be an important part of his national security team and this case has been closed here at the White House as far as we are concerned," Leavitt said on Monday.

"There have been steps made to ensure that something like that can obviously never happen again, and we're moving forward," she said.

The Yemen bombing campaign, which targeted Houthi militants that have been attacking commercial ships in support of Palestinians in Gaza, occurred in mid-March, but was disclosed publicly by Atlantic editor Jeffrey Goldberg on March 24.

Goldberg had been added to the Signal chat alongside several high-ranking officials, including Defense Secretary Pete Hegseth, Vice President JD Vance and CIA Director John Ratcliffe.
