Assemblyman Sebastian Ridley-Thomas abruptly announced his resignation from the California Legislature on Wednesday, citing health reasons.

Ridley-Thomas, a Democrat from Los Angeles, informed Speaker Anthony Rendon (D-Paramount) Tuesday night.

“The reason for this difficult decision is that I am facing persistent health issues,” Ridley-Thomas, 30, said in a written statement on Wednesday. “On December 18th, I underwent surgery for the fifth time this year. Although I expect a full recovery, my physicians advise that I will need an extended period of time to recuperate.”

Earlier this year, Ridley-Thomas was absent from work for more than two weeks. Staff members initially said the absence was a personal leave, then said the time off was due to unspecified medical reasons. His resignation letter on Wednesday offered no additional details.


“When I resume public life, I intend to remain active in civic affairs, where my passion lies,” he said in the statement released by his office.

Ridley-Thomas was first elected to the Assembly in a 2013 special election. He is the son of Los Angeles County Supervisor Mark Ridley-Thomas. Before winning elected office at age 26, the younger Ridley-Thomas worked as an aide for Los Angeles City Councilman Curren Price and managed a 2012 Assembly campaign in San Bernardino County.

His solidly Democratic district includes the west Los Angeles neighborhoods of Westwood, Culver City, Crenshaw and Baldwin Hills. He is chairman of the influential Assembly Revenue and Taxation Committee, which oversees all tax-related legislation. Ridley-Thomas is a proponent of changes in the operation of the state Board of Equalization, though his plan would have allowed the agency to ultimately retain many of its duties. A more substantial shake-up was signed into law by Gov. Jerry Brown in June.

Ridley-Thomas was the author of a bill signed into law in October giving the Los Angeles Unified School District the power to preserve some of its existing single-gender schools. He was unsuccessful, though, in an effort to stop local governments from imposing taxes on streaming video serviceslike Netflix and Hulu.


Ridley-Thomas’ departure will require a special election in 2018. He is the fourth Southern California legislator to leave office this year. The election of Rep. Jimmy Gomez (D-Los Angeles) to Congress also required a special election. The other two lawmakers— Assemblymen Raul Bocanegra (D-Pacoima) and Matt Dababneh (D-Woodland Hills) — stepped down in the wake of allegations of sexual misconduct, which both men have denied. Special elections also will be needed to fill their seats.

“My colleagues and I wish Assemblymember Sebastian Ridley-Thomas all the best going forward as he deals with his health challenges,” Rendon said in a statement. “The Assembly will continue to assist the residents of the 54th Assembly District until a new assemblymember is seated.”
