A federal investigation into former Rep. Eric Swalwell appeared to gain steam this week after agents seized his electronic devices and raided his Washington home over the weekend, even briefly holding the former lawmaker at San Francisco International Airport, a person familiar with the inquiry told the Los Angeles Times.

Swalwell, a Democrat from Dublin, dropped out of the California governor’s race and resigned from Congress in April after allegations that he sexually assaulted a former staffer and acted inappropriately with other young women, which he denied at the time. Before dropping out of the race, polls indicated that Swalwell was among the front-runners.

The source said Swalwell was held on Saturday at SFO and released the same day he was detained for search purposes. Federal prosecutors are using civil rights law to pursue a probe of his conduct as a member of Congress. Authorities in New York and Los Angeles County are conducting separate investigations.

His home was searched on Sunday by federal agents, the source added, based on a search warrant in connection with a civil rights investigation concerning the sexual assault allegations.

Swalwell has denied any wrongdoing, but the accusations upended the California governor’s race and shook Capitol Hill, where both parties reckoned with a culture of secrecy and silence around sexual impropriety.

Another accuser, Lonna Drewes, said at a news conference that she was drugged and raped by the one-time politician in 2018 in Beverly Hills. Drewes said she met Swalwell three times as she was growing her fashion software company and toying with the idea of a political career.

On the third occasion, Drewes said she believes that Swalwell drugged her glass of wine. She said they were supposed to go to a political event and stopped by his hotel room to retrieve some paperwork.

She said she found herself incapacitated despite having had only one drink.

“He raped me and he choked me and while he was choking me I lost consciousness and I thought I died,” she said. “I did not consent to any sexual activity.”

Sara Azari, an attorney for Swalwell, denied Drewes’ characterization of the incident at the time. “Two adults consenting, which is our position, is not against the law,” she said.

The former staffer for Swalwell told the San Francisco Chronicle that Swalwell began sending her nude pictures on Snapchat and messages after she was hired by his office in 2019. She was 21 at the time.

In September of that year, she said she had drinks with the congressman, blacked out and woke up naked in Swalwell’s hotel bed, according to the Chronicle.

In 2024, when she no longer worked for Swalwell, she said she attended a charity event honoring the congressman and met him for drinks afterward. She was intoxicated but recalled Swalwell forcing himself upon her, and that she pushed him away and said, “No,” according to the Chronicle.

Azari said in April that he denied all allegations of sexual misconduct and assault and would pursue “every legal remedy” against those making the claims.

“These accusations are false, fabricated and deeply offensive — a calculated and transparent political hit job designed to destroy the reputation of a man who has spent 20 years in public service,” Azari said.
