Early returns showed strong support for the incumbent in the race for California’s 45th Congressional District, where Derek Tran is running for a second term.

This race drew five Republican challengers: entrepreneur Mark Leonard, Westminster Mayor Chi “Charlie” Nguyen, former Cerritos Mayor Chuong V. Vo, real estate businessman Tom Vo and Westminster Councilmember Amy Phan West.

Tran is an attorney who was first elected to Congress in 2024, defeating incumbent Rep. Michelle Steel. He jumped out to a strong early lead in the first results posted Tuesday. Chuong V. Bo and Nguyen were in a close fight for the second spot.
