Popular News Anchor Arrested By ICE
Federal immigration authorities arrested a staffer for a Democratic California lawmaker during a targeted enforcement operation at a Las Vegas airport, setting off a clash between the Department of Homeland Security and the state legislator who employs him.
Ho-Yin Mo, a field representative for Democratic California Assemblywoman Catherine Stefani, was taken into custody at Harry Reid International Airport on September 17.
Mo, a Hong Kong native and former television news anchor, is now facing removal proceedings while Stefani is publicly demanding his release.
According to the Department of Homeland Security, Mo originally entered the United States legally in 2020 but remained beyond the period he was authorized to stay.
“On January 13, 2020, Mo lawfully entered the U.S. on a temporary basis but illegally overstayed his welcome by failing to depart by May 15, 2020,” a DHS spokesperson said.
The department also directly addressed questions surrounding Mo’s ability to legally work in the United States.
“Work authorization or a pending application do NOT confer legal status in the United States.”
DHS said Mo’s arrest was part of a targeted immigration-enforcement operation at the Las Vegas airport.
The department tied the arrest to a broader Trump administration crackdown on domestic air travel by people it says lack lawful immigration status.
“DHS reversed the horrendous Biden-era policy that allowed aliens in our country illegally to jet around our country,” the department said.
“Under President Trump, DHS will no longer tolerate this. This administration is working diligently to ensure that aliens in our country illegally can no longer fly unless it is out of our country to self-deport.”
But Stefani is pushing back against the federal government’s characterization of her staffer’s situation.
“My message today is simple: I am respectfully calling for Ho Yin Mo’s release as soon as possible,” Stefani said following his detention.
“Ho Yin is a selfless public servant and a valued, legal employee of the California State Legislature serving our San Francisco and Bay Area communities.”
The competing statements highlight an important distinction in the case: Stefani says Mo is legally authorized to work for the California Legislature, while DHS says that employment authorization does not by itself establish lawful immigration status.
Mo’s detention has attracted additional attention because he isn’t an obscure political operative.
Before entering California politics, he was a familiar face to some Bay Area viewers as an anchor and reporter for KTSF Channel 26, a Chinese-language television station.
He later moved into Democratic political organizing.
In 2024, Mo worked as an outreach organizer focused on Asian American and Pacific Islander communities for then-San Francisco Mayor London Breed’s unsuccessful reelection campaign.
His profile apparently made him an attractive political hire.
“When we learned that Mo was available, we immediately saw an opportunity to bring him on board,” Breed spokesman Joe Arellano said at the time. “His visibility through KTSF connects with a broad audience, and his professional background and experience made him a strong fit.”
Mo joined Stefani’s staff in January 2025 as a field representative.
Stefani represents California’s 19th Assembly District, encompassing western San Francisco and northern San Mateo County. Before entering the state Assembly in December 2024, the Democrat served on the San Francisco Board of Supervisors.
Stefani has praised Mo’s work connecting her office with Chinese-American constituents and providing assistance with government services.
“And his work goes far beyond presence. Ho-Yin helps people access affordable healthcare coverage, childcare, and food support. Our whole community eagerly awaits Ho-Yin’s return to his home and his job, where he is loved and adored.”
Federal immigration authorities, however, have taken a different position on the underlying immigration question.
DHS says Mo’s authorized temporary stay expired in May 2020 and maintains that neither a work permit nor a pending immigration application independently gives someone lawful immigration status.
Mo was being held at an immigration detention facility in Nevada while facing removal proceedings that could ultimately result in his deportation to Hong Kong.
His detention also comes as the Trump administration expands immigration-enforcement operations at American airports.
The administration has increasingly targeted visa overstays and other people DHS considers unlawfully present, including some individuals who possess federal work authorization or have pending immigration cases.
That enforcement strategy has generated fierce opposition from immigration advocates and Democratic officials, who argue that people with active immigration cases and work permits should not be swept into detention while those proceedings remain unresolved.
The administration maintains that a pending application or authorization to work does not prevent immigration authorities from enforcing existing removal laws.
Mo’s case now puts that dispute directly inside a Democratic California lawmaker’s office.
A former television journalist who went on to work for two prominent San Francisco Democrats is sitting in federal immigration custody.
His boss says he is a valued employee who should be released.
DHS says he remained in the United States after his authorized stay expired.
And unless his immigration proceedings change that situation, Mo faces the possibility of being removed to Hong Kong.
