WASHINGTON (AP) — The revelation that President Donald Trump's most senior national security officials posted the specifics of a military attack to a chat group that included a journalist hours before the attack took place in Yemen has raised many questions.
Among them are whether federal laws were violated, whether classified information was exposed on the commercial messaging app, and whether anyone will face consequences for the leaks.
Here's what we know so far, and what we don't know.
KNOWN: Signal is a publicly available app that provides encrypted communications, but it can be hacked. It is not approved for carrying classified information. On March 14, one day before the strikes, the Defense Department cautioned personnel about the vulnerability of Signal, specifically that Russia was attempting to hack the app, according to a U.S. official who was not authorized to speak to the press and spoke on the condition of anonymity.
One known vulnerability is that a malicious actor, if they have access to a person's phone, can link their own device to the user's Signal — and essentially monitor messages remotely in real time.
NOT KNOWN: How frequently the administration and the Defense Department use Signal for sensitive government communications, and whether those on the chat were using unauthorized personal devices to transmit or receive those messages. The department put out an instruction in 2023 restricting what information could be posted on unauthorized and unclassified systems.
At a Senate Intelligence Committee hearing Tuesday, Director of National Intelligence Tulsi Gabbard would not say whether she was accessing the information on her personal phone or government-issued phone, citing an ongoing investigation by the National Security Council.
KNOWN: The government has a requirement under the Presidential Records Act to archive all of those planning discussions.
NOT KNOWN: Whether anyone in the group archived the messages as required by law to a government server. The images of the text chain posted by The Atlantic show that the messages were set to disappear in one week.
KNOWN: The chat group included 18 members, including Jeffrey Goldberg, editor-in-chief of The Atlantic. The group, called “Houthi PC Small Group,” likely for Houthi “principals committee” — was comprised of Trump’s senior-most advisers on national security, including Gabbard, Defense Secretary Pete Hegseth, Secretary of State Marco Rubio and CIA Director John Ratcliffe. The National Security Council said the text chain “appears to be authentic.”
NOT KNOWN: How Goldberg got added. Waltz said he built the message chain and didn't know how Goldberg ended up on the chat. He called it a mistake and said he took “full responsibility.”
KNOWN: Just hours before the attack on the Houthis in Yemen began, Hegseth shared details on the timing, targets, weapons and sequence of strikes that would take place.
NOT KNOWN: Whether the information was classified. Gabbard, Ratcliffe and the White House have all said it was not classified, and Hegseth said the same in a post on X. Democrats said that strains credulity considering it contained detailed plans for an upcoming attack on Yemen’s Houthis. Gabbard said the decision on whether the Signal chain should be classified lay with Hegseth.
KNOWN: Hegseth has adamantly denied that “war plans” were texted on Signal, something that current and former U.S. officials called “semantics.” War plans carry a specific meaning. They often refer to the numbered and highly classified planning documents — sometimes thousands of pages long — that would inform U.S. decisions in case of a major conflict, such as if the United States is called to defend Taiwan.
But the information Hegseth did post — specific attack details selecting human and weapons storage targets — was a subset of those plans and was likely informed by the same classified intelligence. Posting those details to an unclassified app risked tipping off adversaries of the pending attack and could have put U.S. service members at risk, multiple U.S. officials said.
Sharing that information on a commercial app like Signal in advance of a strike “would be a violation of everything that we’re about,” said former Defense Secretary Chuck Hagel, who served under President Barack Obama.
NOT KNOWN: If anyone outside the messaging group got access to the Signal texts.
KNOWN: Hegseth is cracking down on unauthorized leaks of information inside the Defense Department, and his chief of staff issued a memo on March 21 saying the Pentagon would use polygraph tests to determine the sources of recent leaks, and prosecute those found to have disclosed unauthorized information.
NOT KNOWN: Whether Hegseth will take responsibility for the unauthorized release of national defense information to a journalist regarding the attack plans on the Houthis. Trump on Wednesday bristled at a suggestion that Hegseth should step down: “He's doing a great job. He had nothing to do with it.”
KNOWN: The revelation of the group chat has troubled some military families, who are required to protect information about the whereabouts and assignments of spouses and loved ones. It also has exasperated some veterans.
NOT KNOWN: How the sharing of the attack plans on Signal may have affected the U.S. service members carrying out the airstrikes in the Middle East.

BANGKOK (AP) — The death toll from Myanmar's powerful 7.7 magnitude earthquake keeps climbing amid rescue efforts.
The military government said Saturday that 1,644 people have been killed, with thousands of others injured and dozens missing.
The earthquake struck midday Friday, followed by several aftershocks, including one that measured 6.4.
In Thailand, the quake rocked the greater Bangkok area, leaving 10 people dead.
Several countries, including Malaysia, Russia and China have dispatched rescue and relief teams.
Here is the latest:
Myanmar’s ruling military said on state television that the confirmed death toll from the 7.7 magnitude earthquake increased to 1,644.
The new total is a sharp rise compared to the 1,002 total announced just hours earlier. The number of injured increased to 3,408, while the missing figure rose to 139 from Friday's quake.
Russia has sent a medical team to Myanmar to care for earthquake victims, a Health Ministry official said.
According to Alexey Kuznetsov, the medics include specialists in infectious diseases, resuscitation and traumatology.
Separately, Russia’s Emergencies Ministry said that two planes carrying Russian rescue workers have landed in Myanmar’s largest city, Yangon.
Earlier, the ministry reported that a mission, including search and rescue teams, canine units, anaesthesiologists and psychologists, was on its way to the disaster-stricken country.
The ministry said that its rescue teams are equipped with “endoscopes and acoustic devices for searching for people in rubble up to 4.5 meters (nearly 15 feet) deep, as well as ground-penetrating radars and thermal imagers.”
Hong Kong sent a group of 51 search-and-rescue personnel to help with earthquake relief efforts in Myanmar. The group includes firefighters and ambulance personnel as well as two search-and-rescue dogs, among others.
The group brings along nine tons (18,000 pounds) of equipment including life detectors and masonry cutting machines, as well as an automatic satellite tracking antenna system that provides network connection, according to a statement on the Hong Kong government’s website.
Satellite photos from Planet Labs PBC analyzed by The Associated Press show the earthquake toppled the air traffic control tower at Naypyitaw International Airport.
The photos taken Saturday show the tower toppled over as if sheered from its base. Debris lay scattered from the top of the tower, which controlled all air traffic in the capital of Myanmar.
It wasn’t immediately clear if there had been any injuries in the collapse, though the tower would have had staff inside of it at the time of the earthquake Friday. It likely also stopped air traffic into the international airport, given all electronics and radar would have been routed into the tower for controllers.
Flights carrying rescue teams from China have landed at the airport in Yangon instead of going directly to the airports in the major stricken cities of Mandalay and Naypyitaw.
A spokesperson for the China International Development Cooperation Agency said that Beijing will provide Myanmar with 100 million yuan ($13.8 million) in emergency humanitarian aid for earthquake relief efforts.
An additional rescue team of 82 people left Bejing, hours after a different team of emergency responders from the Chinese province of Yunnan, bordering Myanmar, arrived in the earthquake-stricken country.
Additionally, 16 members of the Chinese civil relief squad Blue Sky Rescue Team in the city of Ruili, Yunnan, departed to Muse City in northern Myanmar to help with relief efforts, according to state broadcaster CGTN. Chinese authorities also sent a first batch of 80 tents and 290 blankets.
Meanwhile, Chinese President Xi Jinping extended condolences to Myanmar’s leader Min Aung Hlaing.
The earthquake was felt in parts of China's Yunnan province, though casualties were limited. Two people in Ruili suffered minor injuries and 847 homes were damaged, according to authorities. Some high-rise buildings and older houses in urban areas were also partially damaged, but power and water supplies and transportation and communications lines have been restored.
New Zealand Foreign Minister Winston Peters says that his government will support relief efforts “via the International Red Cross Movement."
“Our thoughts are with all those who have lost loved ones, and to everyone else affected,” Peters posted on X.
South Korea will send the aid through international organizations to support recovery efforts following the recent earthquake.
The Foreign Ministry stated on Saturday that Seoul will closely monitor the situation and consider additional support if needed.
