The Trump administration is managing a fresh round of fallout over internal national security deliberations about U.S. strikes in Yemen, after The Atlantic on Wednesday published a fuller transcript of a Signal group chat that included one of its journalists.

The fuller exchange of the extraordinary leak reveals discussions among the country’s top national security officials: cabinet officials and senior White House staff members. In the chat, Defense Secretary Pete Hegseth disclosed specific operational details two hours before U.S. troops launched attacks against the Houthi militia in Yemen. Michael Waltz, the national security adviser, inadvertently added Jeffrey Goldberg, the editor in chief of The Atlantic, to the chat on Signal, a commercial messaging app.

The White House on Wednesday doubled down on its insistence that the information shared was not classified and accused the magazine of overplaying its claims that the administration had revealed “war plans.” The Atlantic published the additional messages after the administration’s repeated assertions that the information was not classified.

The messages show Mr. Hegseth disclosed the exact time that American fighter jets would take off for strikes against the Houthi fighters, a revelation that could have endangered the lives of pilots. The Pentagon would typically share precise timing and sequencing of such strikes only in secure government channels.

Wednesday’s disclosure led to more calls by Democrats for Mr. Hegseth to step down.

Days after the leak went public, Mr. Trump and his aides were still trying to downplay it and have yet to establish a coherent narrative.

Here’s the latest.

The White House has maintained its tactic of deflecting attention from the substance of the leak by attacking the journalist who disclosed it.
