White House dismisses investigation calls, says ‘case closed’ on Signalgate

Trump administration attempts to turn page as it grapples with Houthi resistance and elusive Ukraine-Russia deal.

The White House has said that it is moving on from recent controversy over the mistaken sharing of war plans on commercial messaging app Signal, declaring that the “case has been closed”.

Spokesperson Karoline Leavitt said on Monday that steps had been taken to ensure that the same scenario – which made Jeffrey Goldberg, editor of The Atlantic, privy to a group chat on planned US strikes on Yemen’s Houthis – was not repeated in the future. But she did not elaborate on the measures.

Leavitt said the US was “moving forward”, her statement appearing to end speculation that National Security Advisor Mike Waltz, who invited the journalist to the chat, and Secretary of Defence Pete Hegseth, who shared the sensitive information, would be punished.

Democratic lawmaker Madeleine Dean accused Republicans of showing a “weakness of thought” by deflecting away from the “blunders” of the so-called Signalgate controversy.

“The Trump Administration’s mishandling of sensitive military plans was a staggering failure,” she wrote in a social media post. “Republicans have devolved into ‘what-about-ism.’ It’s time for accountability. It’s time for answers.”
