Background

Kenneth Lee sat on the three-judge federal court in the Central District of California that heard Tangipa v. Newsom, the Republican challenge to California's Proposition 50 congressional map. On 14 January 2026 the Court refused 2-1 to block the map, with Lee dissenting; the Supreme Court denied an injunction pending appeal on 4 February 2026.

Lee is a judge of the US Court of Appeals for the Ninth Circuit. President Donald Trump nominated him on 6 February 2019, the Senate confirmed him on 15 May 2019, and he received his commission on 12 June 2019, taking the seat vacated by Stephen Reinhardt.

In dissent he identified what the plaintiffs called outcome-determinative errors of law, and the plaintiffs built their Supreme Court application on his reasoning. the Court's refusal to intervene left the Proposition 50 map in force for the 3 November 2026 House elections.
