.|upright|left In September 2016, Fong announced his candidacy for the
California State Assembly to succeed Assemblymember
Shannon Grove in the
34th district, who was term-limited. In the
general election, Fong faced Perrin Swanlund, an 18-year-old who recently graduated from West High School, and won the election by a wide margin. Fong was the first Asian American ever to represent Bakersfield in the state legislature, a notable achievement considering the Central Valley's long history of conservative Asian-American political involvement. He was re-elected in
2018,
2020, and
2022, with Fong being redistricted to the
32nd district in 2022. While serving in the Assembly, Fong authored several notable bills, including one aimed at reducing catalytic converter theft, another promoting wildfire prevention through controlled grazing, and a measure to provide firearm training materials in multiple languages. His legislative work has largely focused on enhancing public safety and fostering economic growth. He resigned his Assembly seat on May 24, 2024, after winning the special U.S. House of Representatives election. Fong appeared on both the U.S. House and Assembly ballots in the general election. For his Assembly seat, he endorsed Bakersfield City Councilor Ken Weir, who had secured a second-place spot in the primary via a write-in campaign, encouraging voters to select Weir over himself. Nevertheless, in the general election, Fong won over Weir. == U.S. House of Representatives ==
