White House press secretary Karoline Leavitt said Monday that national security adviser Mike Waltz continues to have President Donald Trump's confidence and that it was done discussing the embarrassing matter of senior officials communicating about plans for an airstrike against the Houthis in Yemen on a commercial messaging app.

"This case has been closed here at the White House as far as we are concerned," Leavitt said.
Waltz added a journalist to the sensitive group chat on the platform Signal, where Defense Secretary Pete Hegseth divulged operational details on the strike and Vice President JD Vance discussed his reservations about the operation.
Leavitt said "there have been steps made to ensure that something like that can, obviously, not happen again," but did not provide any clarity on what those steps were. Lawmakers on Capitol Hill have called for an investigation into the sensitive conversation playing out on Signal.
