Former News Anchor and Democratic Staffer Arrested by ICE

Former News Anchor and California Democratic Staffer Arrested by ICE at Las Vegas Airport

A former Chinese-language television news anchor who now works as a staffer for a California Democratic assemblywoman was arrested by federal immigration authorities at a Las Vegas airport last week, according to the Department of Homeland Security.

Ho-Yin Mo, a field representative for California Assemblywoman Catherine Stefani, was taken into custody by Immigration and Customs Enforcement agents on September 17 at Harry Reid International Airport.

Federal officials say Mo, a Hong Kong native, entered the United States lawfully in January 2020 but remained after the expiration of his authorized stay.

Stefani has disputed the circumstances surrounding his detention and is calling for his release, describing Mo as a valued employee serving constituents in the San Francisco Bay Area.

Who Is Ho-Yin Mo?

Before entering California politics, Mo worked as a reporter and news anchor for KTSF Channel 26, a San Francisco television station serving Chinese-speaking audiences.

He later became involved in Democratic politics, working as an outreach organizer for then-San Francisco Mayor London Breed’s 2024 reelection campaign. Breed ultimately lost that election.

Mo joined Stefani’s legislative staff in January 2025 and works as a field representative, according to reporting and his professional profile. His responsibilities include working with constituents and communities in the San Francisco area.

His background in Chinese-language media also made him a prominent point of contact for Chinese American residents, according to Stefani and local officials.

Why ICE Arrested Him

DHS says Mo entered the United States on January 13, 2020, on a temporary basis and was required to leave by May 15 of that year.

The department says he remained in the country after that deadline.

DHS has emphasized that having employment authorization or a pending immigration application does not, by itself, establish lawful immigration status.

Mo’s case is therefore centered on his immigration status and the circumstances of his continued presence in the United States, rather than an allegation that he committed a violent or other conventional criminal offense.

He is currently being held in immigration custody while removal proceedings continue. Reports indicate that he could face removal to Hong Kong.

Stefani Calls for His Release

Stefani has strongly objected to the detention.

In a statement, she described Mo as a “selfless public servant” and a valued employee of the California Legislature. She said his work has been particularly important when serving Chinese American constituents who may face language or cultural barriers when dealing with government agencies.

Stefani has called for his immediate release.

The dispute illustrates an important distinction in the case: an individual can be legally employed and possess employment authorization while still facing a separate question over whether they have lawful immigration status.

The San Francisco Chronicle reported that Stefani’s office has maintained that Mo was legally employed by the state, while DHS has focused on his immigration status rather than his employment.

San Francisco Mayor Also Calls for Release

The case has drawn attention beyond Stefani’s office.

San Francisco Mayor Daniel Lurie wrote to federal immigration authorities on September 23 asking that Mo be released.

Lurie said Mo has lived in the Bay Area for years and has developed substantial community ties. He also said he did not believe Mo posed a danger or threat to the community.

Several San Francisco supervisors have also expressed support for Mo, emphasizing his work with Chinese American residents.

The local officials’ intervention marks a notable disagreement with the federal government’s handling of the case.

Federal Officials Defend the Arrest

Federal officials have defended the detention by pointing to Mo’s alleged immigration overstay.

Bill Essayli, the first assistant U.S. attorney for the Central District of California, said on social media that immigration laws apply to government employees as well as other people.

DHS has also used the case to emphasize the administration’s broader approach to immigration enforcement, including enforcement actions involving people who remain in the United States after their authorized stay expires.

The federal government has not accused Mo of a violent crime in connection with the arrest.

The Work Authorization Question

One of the more complicated aspects of the dispute involves employment authorization.

Stefani has described Mo as a legal employee of the California Legislature. DHS, meanwhile, has said that work authorization does not automatically provide lawful immigration status.

Those statements are not necessarily contradictory.

Immigration law can permit an individual to work legally while an immigration application or other proceeding is pending even though the person’s broader immigration status remains unresolved. The precise circumstances of Mo’s case, including whether he had a pending application and what protections applied to him, will be relevant to the ongoing proceedings.

A Larger Debate Over ICE Enforcement

Mo’s arrest comes as the Trump administration has expanded interior immigration enforcement across the country.

Federal officials have conducted arrests at airports and other locations while increasing efforts to identify people who authorities say lack lawful immigration status.

The administration argues that immigration laws should be enforced regardless of a person’s occupation or political connections.

Critics, including some California officials, have questioned the detention of people who have established long-standing community ties and employment while pursuing immigration matters.

The disagreement over Mo’s case reflects that larger national debate.

What Happens Next?

Mo remains in federal immigration custody while his case proceeds through the immigration system.

The immediate question is whether immigration authorities or an immigration court will allow him to be released while his proceedings continue.

The case could also clarify the circumstances surrounding his immigration application, employment authorization and alleged overstay.

For now, the basic facts are relatively clear: Ho-Yin Mo, a former Chinese-language television journalist and current California legislative staffer, was arrested by ICE at Las Vegas’s Harry Reid International Airport on September 17. Federal officials say he overstayed his authorized period in the United States, while his employer and San Francisco officials have called for his release.

The underlying immigration proceedings—not the political affiliations of Mo or his employer—will determine what happens next.
