The use of what has been called an unsecured chat on the messaging app Signal, likely on private, not government phones, while various members of the 18-person group were traveling overseas, including in Moscow, constitutes extreme violations of accepted national security practices, experts say. The conversations should have been held via secure communications, inside a Sensitive Compartmented Information Facility (SCIF).

The president, the White House press secretary, the director of national intelligence, the director of the Central Intelligence Agency, the secretary of defense, and other officials — along with top Republican lawmakers and right wing media outlets—have all claimed that information in the Signal chat was not classified.

In sworn testimony on Tuesday before the Senate Intelligence Committee, the Director of National Intelligence and the Director of the CIA both insisted none of the information shared in the Signal chat was classified.

Experts disagree.

“The information Secretary of Defense Hegseth disclosed in the Signal chat was classified at the time he wrote it, especially because the operation had not even started yet, according to a US defense official and another source who was briefed on the operation,” CNN Pentagon and national security correspondent Natasha Bertrand reported.

“It is safe to say that anybody in uniform would be court martialed for this,” the official said, according to Bertrand. “We don’t provide that level of information on unclassified systems, in order to protect the lives and safety of the servicemembers carrying out these strikes. If we did, it would be wholly irresponsible. My most junior analysts know not to do this.”

Barbara Starr, the iconic correspondent who covered the Pentagon on CNN for two decades, focused on National Security Advisor Michael Waltz, who admitted he set up the chat and inadvertently included Goldberg. She wrote:

“Waltz revealed an extraordinary detail when he said there was intel showing the top Houthi missile guy walked into a building. You only know that if you have overhead surveillance, comms intercepts, or an operative on the ground. It means the US had ‘pattern of life’ surveillance. How is that not classified?”

NBC News senior congressional reporter Scott Wong reports that two House Armed Services Committee (HASC) Republicans are denouncing the Trump administration’s handling of Signalgate.

“The White House is in denial that this was not classified or sensitive data. They should just own up to it and preserve credibility,” Rep. Don Bacon (R-NE) said.

After reviewing the Signal text chain, Rep. Scott DesJarlais (R-TN) “said he is concerned about Hegseth sending this detailed information over the messaging app,” Wong also reported.

DesJarlais, chairman of the HASC subcommittee on strategic forces said: “It should have never happened and must not happen again.”

Joseph J. Collins is a retired U.S. Army colonel, professor of national security strategy at the National War College, and former deputy assistant secretary of defense for stability operations. He currently leads the Center for Complex Operations at the National Defense University.

Dr. Collins, responding to Starr’s remarks, wrote: “Important point … this fiasco compromised or potentially compromised sources and methods, possibly including our agents and stringers on the ground.”

Veteran, activist, and Amherst College political science lecturer Paul Rieckhoff declared: “Hegseth must step down or be removed. Any member of the Department of Defense that did this would be in prison. There is no way someone that did this can lead our military as SecDef. And even he knows it.”

“Everyone on this chat probably has to go. Everyone. They all know the rules,” he continued. “Loose lips sink ships. Everyone who’s ever served knows that line. It’s OPSEC 101 that every Private learns in Basic Training. And a f— up like this could have cost American lives. There is no spinning it. Hegseth’s got to go.”

“We can’t have a SecDef who doesn’t follow the same rules and standard he’s expected to hold for millions at DoD,” Rieckhoff added. “There’s no wiggle room. Stakes are too high. Our troops lives depend on it. And our enemies are celebrating.”

Former Transportation Secretary and veteran Pete Buttigieg is one of a handful of top Democrats who have been vociferously contesting the administration’s claims. Based on his extensive military and high-level of government service, late Wednesday he simply wrote: “Well, they lied. Obviously.”

Former CIA lawyer Brian Greer posted screenshots from The Atlantic’s report, and the regulations surrounding what is classified information. He wrote: “This is all very plainly classified at the SECRET level. They all lied. They should all lose their jobs.”

Apparently referencing Tuesday’s Senate Intelligence Committee hearing during which the Director of National Intelligence, Tulsi Gabbard, and CIA Director John Ratcliffe testified, claiming there was no classified information shared, Greer wrote: “There was quite a bit of perjury yesterday.”
