PRESIDENT TRUMP IS SIGNALING the White House will stand by its national security team as the furor grows in Washington over a journalist being added to a group chat discussion about a Yemen bombing campaign.

Trump on Tuesday gave a vote of confidence to national security adviser Mike Waltz, whose account apparently added The Atlantic editor-in-chief Jeffrey Goldberg to the chat group.

The text chain included Vice President Vance, Defense Secretary Pete Hegseth, Secretary of State Marco Rubio, Director of National Intelligence Tulsi Gabbard and CIA Director John Ratcliffe, among others.

"Michael Waltz has learned a lesson and he's a good man,” Trump told NBC.

"It's just something that can happen," he added.

Waltz took shots at Goldberg on Tuesday while saying he had no idea how he got on the text chain.

“This [journalist] in particular I’ve never met, don’t know, never communicated with, and we are looking into and reviewing how the heck he got into this room," Waltz said.

Hegseth is also a key player in the drama, as Goldberg says the Defense chief detailed the administration’s secret war plans against the Iranian-backed Houthis.

“Nobody was texting war plans,” Hegseth said.

“That’s a lie,” Goldberg responded on CNN. “He was texting war plans.”

Goldberg contends he has proof that the officials were discussing secret war plans — including about weaponry, targets and timing — but said he does not plan to publish the highly sensitive material at this point.

The National Security Council said Monday that the chain was authentic.

The White House is publicly backing Hegseth and going on the attack against Goldberg, with press secretary Karoline Leavitt saying he’s “well-known for his sensationalist spin.”

Gabbard and Ratcliffe testified in front of the Senate Intelligence Committee, insisting no classified material was shared on the chat, though questions remain on exactly how that conclusion was reached.

Sen. Mark Warner (Va.), the top Democrat on the Senate Intelligence Committee, called on Hegseth and Waltz to resign, arguing that others in the same position would be fired for mishandling sensitive information.

“This is one more example of the kind of sloppy, careless, incompetent behavior, particularly towards classified information, that this is not a one-off or a first-time error,” Warner said.

Rep. Ted Lieu (Calif.), the vice chair of the House Democratic Caucus and an Air Force veteran, also called on Hegseth to resign, saying his “reckless” handling of sensitive material put the lives of U.S. troops at risk.

“Had that information gotten to the Houthis, American pilots could have been shot down, [and] Navy sailors could have been targeted,” Lieu said.

In addition to questions about whether the officials inadvertently shared classified material with a journalist, it’s unclear whether the national security team is authorized to communicate over Signal, an encrypted app.

Russia-aligned cyber actors have targeted the app for spying in the past.

Rep. Don Bacon (R-Neb.) said there’s “no doubt” that Russia and China were monitoring the U.S. officials’ devices.

“I will guarantee you, 99.99 percent with confidence, Russia and China are monitoring those two phones,” Bacon told CNN’s Manu Raju. “So I just think it’s a security violation, and there’s no doubt that Russia and China saw this stuff within hours of the actual attacks on Yemen or the Houthis.”

Republicans have largely stopped short of calling for consequences over the breach, but acknowledge that a full accounting must take place.

Sen. Jim Risch (R-Idaho), the chair of the Senate Foreign Relations Committee, said he spoke “at length” with Rubio about it.

“This is a matter that’s going to be investigated,” Risch said.

Armed Services Chair Roger Wicker (R-Miss.) said his panel plans to investigate.
