Former Homeland Security officials and federal agents defended a sweeping immigration enforcement operation at a Georgia electric vehicle battery plant last week as a necessary deterrent against illegal hiring, while the companies involved said they are cooperating with authorities and that none of their direct employees were detained.

Homeland Security Investigations (HSI) led what officials described as the largest single-site operation the unit has conducted, detaining hundreds of people at the Hyundai–LG Energy Solution (LGES) joint-venture battery facility under construction near Ellabell, about 20 miles outside Savannah. Former Deputy Assistant Secretary Jonathan Fahey said the raid sends an important signal that employers who hire people unlawfully will face consequences. "This raid was a great deterrent to ensure that people here are working legally," Fahey said on a national broadcast, adding, "Illegal people aren’t allowed to work, and businesses aren’t allowed to profit from using illegal workers."

Homeland Security told reporters that those detained either crossed the U.S. border illegally, were working on expired visas, or were not authorized to work under the Visa Waiver Program. Fox News correspondents at the site relayed that a federal judge issued a search warrant in the matter, and Fahey noted on air that the warrant reflected a finding of probable cause for criminal violations — principally tied to employer conduct.

An attorney representing two people detained at the site told reporters his clients were working in the United States legally. Fahey disputed that claim during the broadcast, saying the warrant established the basis for the law enforcement action. The Justice Department and HSI declined to provide detailed counts or an immediate breakdown of charges pending ongoing investigations and legal processing.

The facility, which has been reported as a multibillion-dollar investment ranging from roughly $4.3 billion to $7.6 billion, is intended to supply batteries to Hyundai’s nearby vehicle assembly plant in Savannah. Georgia state and local officials have described the project as the largest single industrial investment in the state’s history. Construction remains underway at the site.

In statements issued after the operation, LGES said it was "closely monitoring the situation and gathering all relevant details," and that its "top priority is always ensuring the safety and well-being of our employees and partners. We will fully cooperate with the relevant authorities." Hyundai Motor Company told reporters it was aware of the raid and believes that none of those detained were directly employed by Hyundai. "As of today, it is our understanding that none of those detained is directly employed by Hyundai Motor Company," the automaker said, adding that some workers at the site were employed by subcontractors.

The raid drew attention from national political figures and media, reflecting the Trump administration’s emphasis on high-profile immigration enforcement actions. Officials portrayed the operation as part of broader efforts to curb illegal employment and protect U.S. workers. Social media and political commentators reacted with a mix of support and criticism, and the incident added to ongoing debates over immigration enforcement, labor compliance and corporate responsibility in major manufacturing projects.

Federal immigration and criminal proceedings typically involve identification processing, potential charges related to immigration status or employment violations, and, in some cases, referrals to prosecutors for employer-focused investigations. HSI has previously pursued investigations into alleged criminal labor schemes, and officials said that inquiries into workplaces often examine both worker status and employer practices.

Legal advocates and labor groups have in past cases urged clarity and transparency in enforcement actions, urging authorities to distinguish between people who may have been brought to the United States unlawfully and those who were victims of labor trafficking or exploitation. Officials in this instance said they would coordinate with federal prosecutors and continue the investigation.

The companies involved said they would cooperate with authorities as investigations proceed, and local officials said they were monitoring developments and the potential impact on the broader regional economy and workforce. HSI did not immediately release a full accounting of the number of people taken into custody or the specific charges filed, citing ongoing investigative and legal processes. A federal review and any subsequent prosecutions are expected to determine the legal outcomes for those detained and whether employer-directed charges will follow.

As the investigation continues, federal officials and company representatives said cooperation and safety of workers remain priorities. The operation underscores the intersection of immigration enforcement and labor practices at large-scale industrial projects, and it may prompt further scrutiny of hiring practices across similar construction and manufacturing efforts nationwide.
