They certainly broke some important laws. As well as revealing actual operatives and operations, which the journalist (editor-in-chief) was astute enough not to reveal.
"Conceivably, Waltz, by coordinating a national-security-related action over Signal, may have violated several provisions of the Espionage Act ....
The Signal app is not approved by the government for sharing classified information. The government has its own systems for that purpose.
Normally, cellphones are not permitted inside a SCIF, which suggests that as these officials were sharing information about an active military operation, they could have been moving around in public. Had they lost their phones, or had they been stolen, the potential risk to national security would have been severe.
Waltz set some of the messages in the Signal group to disappear after one week, and some after four. That raises questions about whether the officials may have violated federal records law: Text messages about official acts are considered records that should be preserved.
Intentional violations of these requirements are a basis for disciplinary action."
U.S. national-security leaders included me in a group chat about upcoming military strikes in Yemen. I didn’t think it could be real. Then the bombs started falling.
