Offices

WASHINGTON — Federal authorities are investigating letters with “suspicious substances” that have been mailed to congressional and election offices nationwide and are urging recipients to treat the mailings as “potentially hazardous.”

The investigation by the FBI, U.S. Postal Inspection Service and U.S. Capitol Police was first disclosed in a message from the Senate Sergeant at Arms obtained Thursday by The Associated Press. The notice, sent to Senate offices, said that law enforcement officials were working to intercept any additional letters, but “it is possible that some letters may reach their destinations.”

In Congress, the threat appeared limited to the Senate, though the House was monitoring the situation, according to a person familiar with the matter who was not authorized to discuss the investigation publicly.

An FBI statement said the bureau and the Postal Inspection Service were “investigating a series of suspicious mailings sent to various addresses nationwide, including Secretary of State offices and their related election offices.”

“Some of the letters contained an unknown substance and we are working closely with our law enforcement partners to respond to each incident,” the statement read. “We are also working with our partners to identify the individual or individuals responsible for the letters.”

Mailed packages containing a powdery substance led to the evacuation this week of election offices in at least two states, Louisiana and Oklahoma. The Ohio secretary of state said the Postal Service intercepted a package containing a white powder intended for its office and noted that similar mailings had been sent to election officials in multiple states.

News of the letters comes just three weeks before Election Day and is reminiscent of a similar threat in 2023, when election offices in six states received mailings that contained a white powder. In some cases, the incidents disrupted work around local elections.

Some of those letters contained threats and traces of the powerful opioid fentanyl, leading some election offices to stock up on the overdose reversal medication naloxone.

The National Association of Secretaries of State and the National Association of State Election Directors issued a joint statement condemning what they said were threats against election staff.

“Those who administer our elections should never fear for their safety while carrying out their essential duties,” they said in their statement.

Deputy Postal Inspector Brendan Donahue told reporters Thursday that “any threat or attack on election officials is unacceptable” and that “we are also working with our partners on identifying the individual or individuals responsible for the letters.”

United States federal agents have arrested a Saudi national and charged him with planting a hidden audio recording device in a conference room at the California offices of OpenAI, where he was working as an engineer.

Abdulrahman Alfozan, 35, had been working at the AI company since ⁠July 2025, the US Department of Justice said in a statement on Tuesday.

OpenAI discovered the device plugged into a USB port behind a television in an executive conference room at one of its San Francisco buildings on September 30, according to a criminal complaint filed by the Federal Bureau of Investigation (FBI).

Following the discovery, the company placed a camera in the room, which captured Alfozan entering last week and checking behind the television where the listening device had been installed, the FBI alleges.

The case highlights growing security concerns around sensitive AI research as companies and governments compete for the best talent and technology with the potential to alter regional economic and strategic dynamics.

Who is Abdulrahman Alfozan and what is he charged with?

Alfozan has been a legal permanent resident of the US since September 2020.

According to a LinkedIn profile in his name, he studied at ⁠the Massachusetts Institute of Technology (MIT) and the University of California, Berkeley. He previously worked at Meta and Microsoft, it said.

Before he joined OpenAI, he was a venture partner at Raed Ventures, headquartered in Riyadh in Saudi Arabia, which invested “in seed and early-stage startups in Saudi Arabia and MENA”.

Al Jazeera could not independently verify the details mentioned in this LinkedIn profile.

Alfozan made his first court appearance on Tuesday on a charge of “using or endeavouring to use an electronic, mechanical, or other device to intercept oral communications”.

It was not immediately clear if he has legal representation. He is expected to return to court on October 19.

If convicted, Alfozan faces up to five years in prison, a $250,000 ⁠fine, and three years of supervised release.

What happened at OpenAI?

The FBI says a thumb-sized device with a microphone, and which ‌could connect to a camera, had been concealed in toilet paper and placed behind a television set in the conference room. It was installed around September 28, the FBI said. Its stored data was encrypted and inaccessible. Investigators later found a similar device in Alfozan’s personal bag.

In a post on X, OpenAI said it had evidence that the employee intended to place other listening devices throughout sensitive areas of its offices to secretly record meetings.

“At this time, we have no indications of this individual inappropriately accessing or exfiltrating model weights, source code, or customer data. The employee was ⁠terminated,” the company said.

The FBI complaint also alleges that Alfozan used an AI productivity tool to make multiple inquiries about the company’s building addresses, meeting rooms, meeting-room capacities and calendars, despite not having the authority to access these spaces or participate in meetings there.

“This alleged attempt by a Saudi national to steal sensitive communications from OpenAI was taken extremely seriously. Theft of intellectual property involving cutting-edge super intelligence technology poses a serious threat to our national security,” Attorney General Todd Blanche said in a statement on X.

Hasn’t OpenAI been accused of helping to spy on civilians?

In an X post by OpenAI explaining how its own systems were used to trap Alfozan, the company said: “Our security program is designed to protect against a wide range of threat actors, from insider risks to cybercriminals to nation states, and this case is an example of how AI can help address these sophisticated security threats.”

But AI technology is used not only to catch spying, but conversely, to engage in it as well.

In February 2025, an investigation by The Associated Press found that US tech giants had enabled Israel to track and kill people in Gaza and Lebanon through AI and computing services. The AP reported that the Israeli military had bought advanced AI tools from tech companies including OpenAI, the maker of ChatGPT, through Microsoft’s Azure cloud platform, to assist with surveillance.

OpenAI denies having a relationship with the Israeli military.
But OpenAI also faced criticism when it signed a deal with the US Department of Defense in February this year to supply its technology to the US military for use in classified settings, including intelligence gathering. OpenAI’s competitor, Anthropic, refused to sign the same deal unless the Pentagon barred mass surveillance of Americans.

There have been several incidents in which OpenAI models have gone “rogue” by independently breaking out of a testing environment and then hacking into other organisations and even government sites, leading to calls for stronger regulations against unchecked AI surveillance.
