National security adviser Mike Waltz’s team regularly set up chats on Signal to coordinate official work on issues including Ukraine, China, Gaza, Middle East policy, Africa and Europe, according to four people who have been personally added to Signal chats.

Two of the people said they were in or have direct knowledge of at least 20 such chats. All four said they saw instances of sensitive information being discussed.

It’s a more extensive use of the app than previously reported and sheds new light on how commonly the Trump administration’s national security team relies on Signal, a publicly available messaging app, to conduct its work.

“Waltz built the entire NSC communications process on Signal,” said one of the people. All four were granted anonymity because they were not authorized to publicly discuss the private chats.

Veteran national security officials have warned the practice potentially violates regulations on protecting sensitive national security information from foreign adversaries and federal recordkeeping laws if the chats are automatically deleted.
