WASHINGTON (AP) — Defense Secretary Pete Hegseth had an internet connection that bypassed the Pentagon's security protocols set up in his office to use the Signal messaging app on a personal computer, two people familiar with the line told The Associated Press.
The existence of the unsecured internet connection is the latest revelation about Hegseth's use of the unclassified app and raises the possibility that sensitive defense information could have been put at risk of potential hacking or surveillance.
Known as a “dirty" internet line by the IT industry, it connects directly to the public internet where the user's information and the websites accessed do not have the same security filters or protocols that the Pentagon's secured connections maintain.
Other Pentagon offices have used them, particularly if there’s a need to monitor information or websites that would otherwise be blocked.
But the biggest advantage of using such a line is that the user would not show up as one of the many IP addresses assigned to the Defense Department — essentially the user is masked, according to a senior U.S. official familiar with military network security.
But it also can expose users to hacking and surveillance. A “dirty” line — just like any public internet connection — also may lack the recordkeeping compliance required by federal law, the official said.
All three spoke on condition of anonymity to discuss a sensitive matter.
The two people familiar with the line said Hegseth had it set up in his office to use the Signal app, which has become a flashpoint following revelations that he posted sensitive details about a military airstrike in two chats that each had more than a dozen people. One of the chats included his wife and brother, while the other included President Donald Trump’s top national security officials.
Asked about Hegseth’s use of Signal in his office, which was first reported by The Washington Post, chief Pentagon spokesman Sean Parnell said the defense secretary's “use of communications systems and channels is classified.”
“However, we can confirm that the Secretary has never used and does not currently use Signal on his government computer," Parnell said in a statement.
It's the latest revelation to shake the Pentagon. Besides facing questions from both Democrats and Republicans about his handling of sensitive information, Hegseth has dismissed or transferred multiple close advisers, tightly narrowing his inner circle and adding to the turmoil following the firings of several senior military officers in recent months.
Trump and other administration officials have given Hegseth their full support. They have blamed employees they say were disgruntled for leaking information to journalists, with Trump saying this week: “It’s just fake news. They just bring up stories.”
“I have 100% confidence in the secretary,” Vice President JD Vance told reporters Wednesday about Hegseth. ”I know the president does and, really, the entire team does.”
The Pentagon has a variety of secure ways that enable Hegseth and other military leaders to communicate:
— The Non-classified Internet Protocol Router Network can handle the lowest levels of sensitive information. It allows some access to the internet but is firewalled and has levels of cybersecurity that a “dirty” line does not. It cannot handle information labeled as secret.
— The Secure Internet Protocol Router Network is used for secret-level classified information.
— The Joint Worldwide Intelligence Communications System is for top-secret and secret compartmentalized information, which is some of the highest levels of secrecy, also known as TS/SCI.
Hegseth initially was going to the back area of his office where he could access Wi-Fi to use his devices, one of the people familiar said, and then he requested a line at his desk where he could use his own computer.
That meant at times there were three computers around his desk — a personal computer; another for classified information; and a third for sensitive defense information, both people said.
Because electronic devices are vulnerable to spying, no one is supposed to have them inside the defense secretary’s office. Important offices at the Pentagon have a cabinet or drawer where staff or visitors are required to leave devices.
Signal is a commercially available app that is not authorized to be used for sensitive or classified information. It's encrypted, but can be hacked.
While Signal offers more protections than standard text messaging, it’s no guarantee of security. Officials also must ensure their hardware and connections are secure, said Theresa Payton, White House chief information officer under President George W. Bush and now CEO of Fortalice Solutions, a cybersecurity firm.
The communications of senior government officials are of keen interest to adversaries like Russia or China, Payton said.
The National Security Agency issued a warning earlier this year about concerns that foreign hackers could try to target government officials using Signal. Google also advised caution about Russia-aligned hackers targeting Signal users.
Hegseth’s Signal use is under investigation by the Defense Department's acting inspector general at the request of the bipartisan leadership of the Senate Armed Services Committee.
Hegseth pulled the information about the strike on Yemen’s Houthi militants last month from a secure communications channel used by U.S. Central Command. He has vehemently denied he posted “war plans” or classified information.
But the information Hegseth did post in chats — exact launch times and bomb drop times — would have been classified and could have put service members at risk, multiple current and former military and defense officials have said. The airstrike information was sent before the pilots had launched or safely returned from their mission.

BERLIN (AP) — Ukrainian President Volodymyr Zelenskyy on Sunday voiced readiness to drop his country’s bid to join NATO in exchange for Western security guarantees, but rejected the U.S. push for ceding territory to Russia as he held talks with U.S. envoys on ending the war.
Zelenskyy sat down with U.S. President Donald Trump’s special envoy Steve Witkoff and Trump’s son-in-law Jared Kushner. The Ukrainian leader posted pictures of the negotiating table with German Chancellor Friedrich Merz sitting next to him facing the U.S. delegation.
Responding to journalists’ questions in audio clips on a WhatsApp group chat before the talks, Zelenskyy said that since the U.S. and some European nations had rejected Ukraine’s push to join NATO, Kyiv expects the West to offer a set of guarantees similar to those offered to the alliance members.
“These security guarantees are an opportunity to prevent another wave of Russian aggression,” he said. “And this is already a compromise on our part.”
Russian President Vladimir Putin has cast Ukraine's bid to join NATO as a major threat to Moscow's security and a reason for launching the full-scale invasion in February 2022. The Kremlin has demanded tha Ukraine renounce the bid for the alliance membership as part of any prospective peace settlement.
Zelenskyy emphasized that any security assurances would need to be legally binding and supported by the U.S. Congress, adding that he expected an update from his team following a meeting between Ukrainian and U.S. military officials in Stuttgart, Germany.
Washington has tried for months to navigate the demands of each side as Trump presses for a swift end to Russia’s war and grows increasingly exasperated by delays. The search for possible compromises has run into major obstacles, including control of Ukraine’s eastern Donetsk region, which is mostly occupied by Russian forces.
Putin wants Ukraine to withdraw its forces from the part of the Donetsk region still under its control among the key conditions for peace, a demand rejected by Kyiv.
Zelenskyy said that the U.S. had floated an idea for Ukraine to withdraw from the Donetsk and create a demilitarized free economic zone there, a proposal he rejected as unworkable.
“I do not consider this fair, because who will manage this economic zone?” he said. “If we are talking about some buffer zone along the line of contact, if we are talking about some economic zone and we believe that only a police mission should be there and troops should withdraw, then the question is very simple. If Ukrainian troops withdraw 5–10 kilometers, for example, then why do Russian troops not withdraw deeper into the occupied territories by the same distance?”
Zelenskyy described the issue as “very sensitive” and insisted on a freeze along the line of contact, saying that “today a fair possible option is we stand where we stand.”
Putin's foreign affairs adviser Yuri Ushakov told the business daily Kommersant that Russian police and national guard would stay in parts of the Donetsk region even if they become a demilitarized zone under a prospective peace plan.
Ushakov warned that a search for compromise could take a long time, noting that the U.S. proposals that took into account Russian demands had been “worsened” by alterations proposed by Ukraine and its European allies.
Speaking to Russian state TV in remarks broadcast Sunday, Ushakov said that “the contribution of Ukrainians and Europeans to these documents is unlikely to be constructive," warning that Moscow will “have very strong objections.”
Ushakov added that the territorial issue was actively discussed in Moscow when Witkoff and Kushner met with Putin earlier this month. “The Americans know and understand our position," he said.
Merz, who has spearheaded European efforts to support Ukraine alongside French President Emmanuel Macron and U.K. Prime Minister Keir Starmer, said Saturday that “the decades of the ‘Pax Americana’ are largely over for us in Europe and for us in Germany as well.”
He warned that Putin's aim is “a fundamental change to the borders in Europe, the restoration of the old Soviet Union within its borders.”
“If Ukraine falls, he won’t stop,” Merz warned on Saturday during a party conference in Munich.
Putin has denied plans to restore the Soviet Union or attack any European allies.
Ukraine’s air force said that Russia overnight launched ballistic missiles and 138 attack drones at Ukraine. The air force said 110 had been intercepted or downed, but missile and drone hits were recorded at six locations.
Zelenskyy said Sunday that hundreds of thousands of families were still without power in the south, east and northeast regions and work was continuing to restore electricity, heat and water to multiple regions following a large-scale attack the previous night.
The Ukrainian president said that in the past week, Russia had launched over 1,500 strike drones, nearly 900 guided aerial bombs and 46 missiles of various types at Ukraine.
Russia’s Defense Ministry said that air defenses downed 235 Ukrainian drones late Saturday and early Sunday.
In the Belgorod region, a drone injured a man and set his house ablaze in the village of Yasnye Zori, regional Gov. Vyacheslav Gladkov said.
Ukrainian drones struck an oil depot in Uryupinsk in the Volgograd region, triggering a fire, according to regional Gov. Andrei Bocharov.
In the Krasnodar region, the Ukrainian drones attacked the town of Afipsky, where an oil refinery is located. Authorities said that explosions shattered windows in residential buildings, but didn’t report any damage to the refinery.
