The group chat appears to suggest that the officials' discussion was one that had continued from the White House Situation Room, one of the most secure venues in the US government.

Karlin said these types of conversations should take place in a secure space, in the Pentagon or in the Situation Room in the White House, not in a Signal group chat.

This drastic shift was pitched as part of a broader reconfiguration of CNN's lineup, which also bumps “The Situation Room” host Wolf Blitzer out of his long-held evening berth into Acosta’s former slot where he's set to co-anchor with Pamela Brown starting in March.

The network is moving “The Situation Room” with anchors Wolf Blitzer and Pamela Brown into the 10 a.m.

“The Situation Room” with Blitzer and Pamela Brown will air from 10 a.m. to noon Eastern.
