Rep. Anna Paulina Luna, R-Florida, says she is preparing to file a motion to expel Rep. Eric Swalwell, D-Calif., following allegations of sexual assault made by a former staffer.

Luna announced the move in a series of posts on social media, arguing that Swalwell should not remain in Congress amid the accusations. She also called on him to resign, framing the issue as one of accountability for elected officials.

“He should not be allowed to stay in Congress,” Luna wrote, adding that political considerations should not override what she described as basic standards of conduct.

Swalwell has denied the allegations, calling them “flat false” and stating they “did not happen.” He also said he would fight the claims while apologizing to his family for what he described as past “mistakes in judgment.”

The controversy comes as Swalwell is running in California’s gubernatorial race, where some Democratic figures have already urged him to withdraw. His campaign has also seen internal fallout, with co-chairs Rep. Jimmy Gomez and Rep. Adam Gray stepping down and calling for him to exit the race.

Despite that pressure, few Democrats have publicly called for his resignation from Congress.

Luna’s proposed motion would require significant support in the House to advance, making its outcome uncertain. However, the effort adds to growing scrutiny surrounding Swalwell as both his political future and the allegations against him continue to unfold.

California’s primary election is scheduled for June 2, with the top two finishers advancing to the general election in November.
