Trump administration officials and allies are concerned, angry and confused about the response — led by national security adviser Mike Waltz — to the leak of a group chat conversation that included plans for an attack on Houthi rebels in Yemen.

Over the last 24 hours, President Donald Trump and officials in his administration have appeared to downplay the seriousness of the leaked Signal group chat first revealed by The Atlantic’s Jeffrey Goldberg, who was accidentally included in the discussion and later published his account of the snafu.

“The White House is in denial that this was not classified or sensitive data,” said Rep. Don Bacon, a Nebraska Republican and former Air Force general. “They should just own up to it and preserve credibility.”
