In a significant political move, King County Executive Dow Constantine has nominated three seasoned politicians—Karen Keiser, Julia Patterson, and De’Sean Quinn—to succeed Dave Upthegrove on the County Council. Keiser, a former state senator, has a long history of public service, while Patterson previously served on the King County Council for twelve years. Quinn brings his experience from the Tukwila City Council, where he has been a member since 2008. The County Council is tasked with selecting a nominee within 60 days, with the chosen individual serving until the certification of the next general election in November. This appointment is particularly important for the diverse communities in District 5, which encompasses parts of Kent, Tukwila, Renton, and surrounding cities.

Constantine expressed confidence in the nominees' capabilities to protect the interests of District 5 residents. This nomination process is part of a state-mandated procedure established in 2010, ensuring that county executives nominate candidates for council vacancies. The decision to appoint a new council member will significantly impact local governance in the region.
