Calls for Waltz's Resignation Grow Amid Report of At Least 20 Sensitive Signal Group Chats

U.S. National Security Adviser Mike Waltz and members of his staff have created at least 20 group chats on the encrypted messaging app Signal to coordinate official work on sensitive policy issues around the world, four people who were added to such groups told Politico.

Waltz was already under fire for a group chat about the U.S. bombing Yemen when the report broke. Politico's Dasha Burns wrote on Wednesday that "none of the four individuals said they were aware of whether any classified information was shared, but all said that posts in group chats did include sensitive details of national security work."

The anonymous sources told Politico that the group chats involved policy issues involving China, Ukraine, Gaza, the Middle East, Europe, and Africa. One of them said, "It was commonplace to stand up chats on any given national security topic," one of the four sources told the outlet.

The Politico article comes a day after The Washington Post reported that Waltz and other members of President Donald Trump's National Security Council conducted official government business via their personal Gmail accounts, which are far less secure than Signal chats.

The fresh revelations also come as "Signalgate"—in which Waltz, Defense Secretary Pete Hegseth, and other top Trump administration officials added a journalist to a Signal group chat about plans to bomb Yemen—still smolders.

Calls for Waltz's resignation or firing, which were already numerous in the wake of Signalgate, mounted Wednesday.

"Waltz must resign. Hegseth must resign," Rep. Ted Lieu (D-Calif.), a member of the House Foreign Affairs Committee, said on the social media site Bluesky. "There must be accountability for this administration's dangerous disregard for our national security."

Referring to the Signal group chats, Rep. Jimmy Gomez (D-Calif.) asked on the social media site X, "How many more are there?"

"Even Trump allies say this doesn't pass the smell test," he added. "National Security Adviser Waltz and Pete Hegseth need to be fired."
