FIRST ON FOX – Sen. Josh Hawley, R-Mo., asked the Justice Department on Thursday to investigate a Chinese-owned self-driving trucking company, one of the largest in the U.S., citing allegations that it had shared proprietary data and other sensitive technology with state-linked entities in Beijing. 

The letter, sent to U.S. Attorney General Pam Bondi and previewed exclusively to Fox News Digital, asks the Justice Department to open a formal investigation into the autonomous truck company TuSimple Holdings, a Chinese-owned company and one of the largest self-driving truck companies in the U.S. 

In it, Hawley cites recent reporting from the Wall Street Journal that alleges that TuSimple "systematically shared proprietary data, source code, and autonomous driving technologies" with Chinese state-linked entities— what he described as "blatant disregard" of the 2022 national security agreement with the Committee on Foreign Investment in the United States, or CFIUS.

"These reports also revealed communications from TuSimple personnel inside China requesting the shipment of sensitive Nvidia AI chips and detailed records showing ‘deep and longstanding ties’ with Chinese military-affiliated manufacturers," Hawley said.

He noted that to date, TuSimple "has not faced serious consequences" for sharing American intellectual property with China, despite having continued to share data with China after signing a national security agreement with the U.S. government in 2022, which was enforced by the Committee on Foreign Investment in the U.S.

"If the reports about TuSimple are accurate, they represent not just a violation of export law, but a breach of national trust and a direct threat to American technological leadership," Hawley said.

"The American people deserve to know how and why a supposedly U.S.-based company was allowed to serve as a conduit for the transfer of sensitive innovations to the Chinese Communist Party," he added.

The letter asks Bondi and the Justice Department to take certain steps to investigate the company's actions, as alleged by the recent reports – including investigating whether TuSimple provided protected information to any Chinese-based entities, and what activities were covered by the company's national security agreement with CFIUS, struck more than two years ago. 

Hawley also asked Bondi what actions, if any, DOJ has taken to date to ensure that Bot Auto—a new Texas-based self-driving vehicle company staffed by many former TuSimple employees, "is not engaging in similar behavior."

According to the Wall Street Journal report, TuSimple's actions helped shape new Commerce Department regulations, which blocked the sale of internet-linked cars and different components with links to China. According to the report, a CFIUS investigation determined TuSimple's tech sharing did not violate the official national security agreement— but the company was fined for other infractions, and ultimately paid out a $6 million settlement. 

The letter comes as Hawley, who chairs the Senate Judiciary Committee's Subcommittee on Crime and Counterterrorism, has emerged as one of the Senate's more vocal critics of the Chinese Communist Party, especially as it relates to the conduct of certain U.S. companies, and the sharing of certain intellectual property.
