You should read the release that CISA put out [0]. The use of Signal for classified discussions is not a suggested use. True, it's not explicitly forbidden, but people entrusted with that access should know better.

Saying that CISA approved Signal (and, in right-wing sources, saying "Biden administration CISA") is an attempt to minimize and distract.

They shouldn't have been texting classified information. Full stop.

What classified info was in the chat? The only reference I saw to classified info was explicit references to getting out of that medium to discuss classified info

I have not verified this, but reporting suggests they had targeting data down to the names of individuals in Yemen, as well as flight times and originating sources for the airstrikes, which if leaked would be very valuable to whatever air defenses were in the country. It is not clear if intelligence sources were also potentially compromised.
