Members of Congress and national security staffers were stunned Monday by a bombshell report that top Trump administration officials — including the vice president and Defense secretary — discussed war plans in a Signal group chat.

Many raised concerns about the potential mishandling of classified information as well as sensitive details regarding U.S. war plans.

“Only one word for this: FUBAR,” Rep. Pat Ryan (D-N.Y.), an Army veteran who sits on the Armed Services Committee, wrote on X. “If House Republicans won’t hold a hearing on how this happened IMMEDIATELY, I’ll do it my damn self.”

“Get the fuck out,” said one Democratic congressional aide, capturing a general reeling on Capitol Hill about broken security protocols. It’s an “operational security nightmare,” the aide said. The aide, and others, were granted anonymity to be candid about a sensitive security issue involving the administration.

In the report in The Atlantic, the magazine’s editor revealed that he had accidentally been added to a group chat on the secure messaging app Signal where senior members of the Trump administration were discussing plans for airstrikes on Houthi rebels in Yemen.

Some on Capitol Hill used it as an opportunity to hit back at the Trump administration’s foreign policy.

“Amateur hour,” Sen. Ruben Gallego of Arizona (D), a Marine veteran, wrote in a post on X. “These are the geniuses that are also selling out Ukraine and destroying our alliances all around the world. No wonder Putin is embarrassing them at the negotiation table.”
