A Pentagon watchdog has determined that Defense Secretary Pete Hegseth risked the safety of U.S. servicemembers by sharing sensitive military information on the Signal messaging app, according to a source who has reviewed the forthcoming inspector general report.
The report, which is expected to be released as early as Thursday, was launched after a journalist for The Atlantic revealed in March that he had been added to a chat on the encrypted messaging app in which Hegseth and other top officials were discussing plans for U.S. airstrikes against Houthi rebels in Yemen.
A summary of the report provided to NPR finds that had a foreign adversary intercepted the intelligence discussed in the chat, it would have endangered both U.S. servicemembers and the mission at large.
The investigation was conducted by Pentagon Inspector General Steven Stebbins. His findings were shared with NPR by a source who has seen the document but was not authorized to discuss it publicly.
The report concludes that Hegseth, who sent the information about targets, timing and aircraft to two Signal groups, including his wife and brother, violated Pentagon policies about using personal phones for official business. Hegseth would not sit for an interview with investigators, the report said, and would only provide a written response.
In his response, Hegseth stated that he was able to declassify information; the inspector general did not determine whether Hegseth had declassified information in the chat by the time it was shared, but acknowledged that, as secretary of defense, he had the authority to do so.
Hegseth also told the inspector general that he believed the investigation was political and that he lacked faith in Stebbins, according to the source.
In a statement, chief Pentagon spokesman Sean Parnell said the findings absolved Hegseth of any wrongdoing.
“The Inspector General review is a TOTAL exoneration of Secretary Hegseth and proves what we knew all along — no classified information was shared. This matter is resolved, and the case is closed,” Parnell said.
In a separate statement, White House press secretary Karoline Leavitt defended President Trump’s national security team and its handling of sensitive information.
“This review affirms what the Administration has said from the beginning — no classified information was leaked, and operational security was not compromised,” Leavitt said.
The report is the product of months of investigation. The probe was launched in April in response to a request from the top Republican on the Senate Armed Services Committee, Roger Wicker of Mississippi, and Jack Reed, the panel’s top Democrat.
Over the course of the investigation, the report states, Hegseth only provided a few of his Signal messages to the inspector general. As a result, Stebbins was forced to rely mostly on screenshots of the chat from the Atlantic, according to the source.
One member of the Armed Services committee, Arizona Democrat Mark Kelly, responded to the report by saying “it’s pretty clear he shouldn’t have been using his cell phone and an unsecure app, unofficial app with regards to DOD, to be sharing that kind of information.”
“It’s not too hard to see how our adversaries can get that information and pass it on, to the Houthies in this case, and put those lives at risk,” Kelly said.
The report’s expected release comes as Hegseth faces pressure to answer for the administration’s controversial campaign to strike boats in the Caribbean Sea that are allegedly carrying drugs to the U.S. from South America. One of those strikes has forced the administration to answer questions about whether the U.S. fired on the survivors of a bombing on Sept. 2, a move that military experts say could constitute a war crime if the administration’s claim to be at war with narco traffickers is to be accepted.
Hegseth’s leadership at the Pentagon has been dogged by controversy. Critics have highlighted that the Army National Guard combat veteran and former Fox News host lacks the same level of experience as his predecessors at DOD.
In his Senate confirmation hearing, the social conservative told lawmakers that “lethality, meritocracy, warfighting, accountability and readiness” were his top priorities for the role. Since being sworn in, he’s overseen the agency through drastic changes, firing several top officials, placing restrictions on troops and veterans that are transgender and rebranding the agency as the Department of War.
The White House reiterated continued confidence in Hegseth on Wednesday, with Leavitt saying in a statement that, “President Trump stands by Secretary Hegseth.”

Sixteen of the 18 passengers transferred to the U.S. from a cruise ship where there was an outbreak of hantavirus arrived in Omaha, Neb., on Monday for evaluation after disembarking the vessel in Spain’s Canary Islands over the weekend.
Of the 15 U.S. citizens and one dual U.S.-British citizen who arrived in Nebraska, all but one are currently being housed in the National Quarantine Unit. That patient tested positive for the virus and was being housed in the Nebraska Biocontainment Unit, officials said at a Monday news conference. The 15 people in the quarantine unit will continue to be monitored for signs of the illness.

Nebraska may seem an unlikely location to process these individuals, but it is home to the National Quarantine Unit — the only federally funded quarantine unit in the U.S. — and the separate Nebraska Biocontainment Unit. They are highly specialized facilities located at the University of Nebraska Medical Center (UNMC) and widely considered among the best in the world.
The $1 million, five-room biocontainment unit was dedicated in 2005. It was a joint project with Nebraska Health and Human Services and the UNMC. It is set up to safely provide medical care for patients with highly hazardous and infectious diseases and was used in 2014 to treat two doctors infected with Ebola. The National Quarantine Unit was completed in late 2019. It cost nearly $20 million, according to the Associated Press. Both facilities were used during the COVID-19 epidemic.
“We are prepared for situations exactly like this,” Dr. Michael Ash, CEO of Nebraska Medicine, said in a statement. “Our teams have trained for decades alongside federal and state partners to make sure we can safely provide care while protecting our staff and the broader community. We are proud to support this national effort.”
Two additional U.S. passengers on the cruise ship — a couple, with one showing symptoms of hantavirus — were transferred for monitoring to Emory University Hospital, where another advanced biocontainment facility is located.
When the biocontainment unit was first dedicated more than 20 years ago, the biggest concerns were anthrax attacks and severe acute respiratory syndrome, more commonly known as SARS, Dr. Phil Smith, who spearheaded the efforts at Nebraska Medical Center to create the biocontainment unit, told the AP in 2020. Smith died last year.

The quarantine unit features 20 negative-pressure rooms designed to keep potentially harmful particles from escaping by maintaining lower air pressure inside than outside the rooms. The single-occupancy rooms provide patients with attached bathrooms, exercise equipment and Wi-Fi, according to the medical center.
“We have protocols in the quarantine unit that provide for safe care of these of these persons, including just all the activities of daily living so that they can … have a comfortable stay but also have it in an area that’s protected and limits spread of the pathogen,” Dr. Michael Wadman, the medical director of the National Quarantine Unit, said at a Friday news conference.
The biocontainment unit, by contrast, is a patient-care space where people are able to receive medical treatment, Dr. Angela Hewlett, medical director of the biocontainment unit, told reporters Monday.
She emphasized that the facility — which has a 10-bed capacity — operates independently from the quarantine unit and has its own dedicated air-handling system. “We don’t share [it] with any of the rest of the facility,” she said, noting that the unit uses rooftop HEPA filtration and is designed “very differently” from what most people typically imagine in a hospital setting.

Nebraska Gov. Jim Pillen, speaking at Monday’s news conference, welcomed the recently arrived patients, who are among nearly 150 people from 23 different countries who were aboard the MV Hondius when the illness most commonly transmitted to humans through contact with infected rodents broke out. As of Monday, the World Health Organization has reported at least nine cases of hantavirus, including three deaths.
“We’re glad that you’re here,” Pillen said. “We’re going to ensure that you have the best world-class care possible.”
Pillen also sought to reassure Nebraskans that the facilities are safe and secure: “We’re working diligently to ensure no one leaves the security in an unsecured way at an inappropriate time,” he said. “No one poses a risk to public health, just walking out the front door of the streets of Omaha.”
The hantavirus outbreak on the cruise ship has been identified as the Andes strain of the illness, one that can be spread, though rarely, from person-to-person, according to the Centers for Disease Control and Prevention. It can cause severe respiratory disease, with early flu-like symptoms.
“The Andes variant of this virus does not spread easily, and it requires prolonged, close contact with someone who is already symptomatic,” according to Adm. Brian Christine, the assistant secretary for health at the U.S. Department of Health and Human Services, who spoke at Monday’s news conference. “Even so, we have taken this situation very seriously from the very start.”
“The risk of hantavirus to the general public remains very, very low,” he said.
The full quarantine period for hantavirus is 42 days, Christine said, but he added that the patients would be allowed to go home if they remained asymptomatic.
“Right now, the passengers that are all in the assessment phase — they’re going to be here for at least a few days while we do assessments and the coordination on what happens next,” he said, adding that they had the option to remain in the quarantine facility for the full period, for “the safest and most effective option for them.”

We’re working diligently to ensure no one leaves the security in an unsecured way at an inappropriate time. No one who poses a risk to public health is walking out the front door of the streets of Omaha or beyond.

The man charged with attempting to assassinate President Donald Trump at the White House Correspondents’ Association dinner last month pleaded not guilty at a Monday arraignment in federal court.
Cole Tomas Allen, 31, wearing an orange shirt and trousers, was handcuffed and shackled as he was brought into the courtroom in Washington, D.C., federal court. His handcuffs were attached to a chain around his waist, which clanked as he was led to the defense table.
Speaking on behalf of Allen, federal public defender Tezira Abe said her client “pleads not guilty to all four counts as charged,” including attempting to assassinate the president of the United States, in connection with the April 25 incident at the Washington Hilton hotel.
Assistant U.S. Attorney Charles Jones advised the court that they plan to start producing their first tranche of discovery to the defense by the end of the week.
Officials said Allen, a California teacher and engineer, was armed with multiple guns, as well as knives, when he sprinted through a security checkpoint near the event where Trump and other White House officials had gathered with journalists.
He was arrested after an exchange of gunfire with a U.S. Secret Service officer who fired at him multiple times, a criminal complaint said. Allen was not shot during the exchange. The officer, who was wearing a ballistic vest, was shot once in the chest, treated at a hospital and released.
Trump and top members of his Cabinet and Congress were quickly evacuated from the room as others ducked under tables.
Allen was initially charged with attempting to assassinate the president, transportation of a firearm and ammunition through interstate commerce with intent to commit a felony, and discharge of a firearm during a crime of violence. On Tuesday, a federal grand jury indicted him on a new charge in the shooting of a Secret Service agent.
Moments before the attack, Allen had sent his family members a note apologizing and criticizing Trump without mentioning the president by name, according to a transcript of some of his writings provided to NBC News by a senior administration official. Allen also wrote that “administration officials (not including Mr. Patel)” were “targets.”
He also appeared to have taken a selfie in his hotel room. Prosecutors said Allen, who was dressed in a black button-down shirt and black pants, was “wearing a small leather bag consistent in appearance with the ammunition-filled bag later recovered from his person,” as well as a shoulder holster, a sheathed knife, pliers and wire cutters.
Officials have said they believe Allen had traveled by train from California to Washington, D.C., before checking into the hotel.
Allen’s sister, Avriana Allen, told law enforcement that her brother would make radical comments and constantly referenced a plan to fix the world, but said their parents were unaware that he had firearms in the home and that he would regularly train at shooting ranges.
Records show that he had purchased a Maverick 12-gauge shotgun in August 2025 and an Armscor Precision .38 semiautomatic pistol in October 2023.
After his arrest, Allen told the FBI that he did not expect to survive the incident, according to Assistant U.S. Attorney Jocelyn Ballantine. He was briefly placed on suicide watch at the Washington, D.C., jail, where he’s being held.
Allen is expected to appear in court for a June 29 hearing.
At Monday’s arraignment, his legal team said they plan on asking for the “entire office” of the U.S. attorney for the District of Columbia to be recused because of U.S. Attorney Jeanine Pirro’s apparent involvement in the case in a “supervisory role.” Federal public defender Eugene Ohm said some of the evidence they receive from the government will further inform that decision.
