On December 10, 2024, State Rep. Tina Orwall was appointed by the King County Council to succeed retiring Sen. Karen Keiser in the Washington State Senate. Orwall emerged from a competitive selection process that included nominees Mia Gregerson and Melissa Chaudhry, both of whom were recognized for their dedication to public service. With a legislative career that began in 2009, Orwall has been a prominent advocate for mental health policies, housing stability, and victims' rights.

In her remarks following the appointment, she expressed gratitude for the trust and support from her colleagues, highlighting the importance of community partnership. The council acknowledged the qualifications of all nominees, underscoring the difficulty of their decision. Orwall's term will last until January 2027, and a special election is set for 2026 to determine her successor. The appointment reflects a significant shift in leadership within the 33rd Legislative District. Edwin Obras has been selected to fill Orwall's former House seat, ensuring continuity in representation for the community.
