Sheila Jackson Lee's career in Congress was marked by significant legislative achievements, including the establishment of Juneteenth as a federal holiday and the reauthorization of the Violence Against Women Act. Her dedication to civil rights was reflected in her efforts to address systemic injustices and support underserved communities. Her work not only impacted her constituents in Houston but also resonated nationally, earning her respect and admiration from colleagues across the political spectrum.

Following Jackson Lee's death, the process to fill her congressional seat has begun, with Harris County Democrats facing a tight deadline to select a candidate for the November ballot. The Texas Election Code outlines a two-step process involving a vote by precinct chairs and possibly a special election called by the governor. This has sparked interest from several potential candidates, reflecting the significant impact of Jackson Lee's leadership and the importance of her seat in the closely divided House.

Tributes have poured in from across the political spectrum, highlighting Jackson Lee's role as a unifying figure and a relentless advocate. Figures from President Joe Biden to local leaders and international voices have expressed their condolences, acknowledging her tireless work and the deep impact she had on her community and beyond. Her passing is mourned not only as a loss of a political leader but as a personal loss to many who knew her as a friend and mentor.
