Labor Leader, EMILY's List President, Appointed Senator
Laphonza Butler's path to the United States Senate was forged in the labor halls of California rather than the campaign trail. Raised in Mississippi and a graduate of Jackson State University, she moved to California and built a career as a union organizer, eventually becoming president of SEIU Local 2015 — representing 400,000 home care and nursing facility workers and making it the largest local union in the country. Her organizing work established her as a major force in California progressive politics and gave her deep ties to the Democratic infrastructure.
She served as a senior advisor and strategist to Senator Kamala Harris and joined the Harris 2020 presidential campaign before Harris was selected as Biden's running mate. After the campaign, Butler took the helm of EMILY's List in 2021, leading the nation's most prominent organization dedicated to electing pro-choice Democratic women. The role placed her at the center of Democratic party politics during the post-Roe mobilization period following the Supreme Court's 2022 Dobbs decision.
When Senator Dianne Feinstein died in office in September 2023, Governor Gavin Newsom appointed Butler to the vacant seat — making her only the second Black woman to serve in the U.S. Senate at the time (alongside Senator Warnock's Georgia colleague and others). Butler announced she would not seek election to the full term, stepping aside to allow the 2024 field to develop without an incumbent advantage. Adam Schiff won the subsequent race.
- Laphonza Butler (D-CA) was appointed to the US Senate in October 2023 following the death of Dianne Feinstein, serving until January 2025 when Adam Schiff took office after winning the 2024 special election.
- She was the first Black lesbian senator in US history and the first openly LGBTQ+ senator of color, serving approximately 14 months before her term ended.
- Butler did not run for election to the seat — her appointment was temporary, allowing California Governor Gavin Newsom to fill the vacancy while a proper election took place.
- Before her Senate appointment, she was a leading labor organizer — serving as president of EMILY's List and before that as president of the Service Employees International Union (SEIU) California.
Key Policy Areas
Worker Organizing & Wages
Butler's entire career before the Senate was rooted in labor organizing. She is a strong proponent of unionization rights, raising the federal minimum wage, and expanding protections for home care workers — one of the most underpaid and underprotected sectors of the workforce. Her SEIU background gives her credibility with organized labor that few elected officials can match.
Abortion Access & Women's Health
As president of EMILY's List during the post-Dobbs era, Butler was at the forefront of the Democratic effort to make abortion polling a central electoral issue. She led EMILY's List through record fundraising cycles and the 2022 midterm period. Her Senate votes consistently reflected full support for codifying Roe protections and expanding abortion access.
Black Political Empowerment
Butler is a prominent voice for Black political representation and economic equity. Her appointment to the Senate was explicitly tied by Newsom to his commitment to Black representation in the chamber. She has been a consistent advocate for policies addressing racial wealth gaps, healthcare disparities, and the political underrepresentation of Black women in elected office.
The Feinstein Appointment
Senator Dianne Feinstein's death on September 29, 2023 created a vacancy in one of the most powerful Senate seats in the country. Governor Newsom had previously pledged to appoint a Black woman to fill any California Senate vacancy, and Butler was his choice. The appointment came amid intense speculation about California's 2024 Senate majority, which was already drawing major candidates including Adam Schiff, Katie Porter, and Barbara Lee — all House members seeking to move up.
Butler's decision not to seek election to the full term was significant. It meant she served as an appointed senator for roughly 15 months before returning to private life in January 2025, when Schiff was sworn in. During her brief tenure she voted consistently with the Democratic caucus, focused on constituent services for California, and used her platform to continue advocating for labor and reproductive rights. She became the second Black woman to represent California in the Senate and only the fourth Black woman senator in American history.

Medicaid & Social Safety Net Policy
Sen. Laphonza Butler (D-CA) served in the Senate during the critical 2023-2025 period when debates over Medicaid and the social safety net intensified. Republican proposals to restructure Medicaid — including work requirements and per-capita caps — were among the most contentious healthcare policy fights of the era. Butler, an appointee with deep roots in labor and progressive politics, was an outspoken opponent of cuts to federal healthcare programs. California has the largest Medicaid program in the country (Medi-Cal), and any federal restructuring would affect millions of California residents directly. Her brief Senate tenure placed her at the center of debates over the healthcare issues that continue to define the Democratic Party's domestic policy agenda. She chose not to run in the 2024 special election to fill the remainder of the term.
