First sworn into the Texas House of Representatives in 2021, David Cook is serving his second term representing Texas House District 96, which includes several cities in Tarrant County, such as Arlington, Fort Worth, and Mansfield. Cook, who earned his degrees from Stephen F. Austin State University and Texas A&M University School of Law, leverages extensive legal expertise as the Managing Partner at Harris Cook L.L.P., a firm he co-founded with the late State Senator Chris Harris, and is recognized as Board Certified in Family Law by the Texas Board of Legal Specialization.

During the 88th Texas Legislature, Cook was appointed Vice Chairman of the House Criminal Jurisprudence Committee and participated as a member of the House Calendars and Juvenile Justice & Family Issues Committees. He also holds positions on the Texas House Republican Caucus Policy Committee, the Innovation & Technology (IT) Caucus Policy Committee, and the Criminal Justice Reform, Manufacturing, and Sportsmen Caucuses. His dedicated service has earned him recognition as a 2023 GOPAC “Emerging Leader.”

Representative Cook has distinguished himself by sponsoring and co-authoring various impactful bills, with particular emphasis on education, safety, and technology. Notable among these is House Bill 2615, which aims to establish foundation and trade diploma programs within public school districts, facilitating vocational paths for students and aligning educational outcomes with the labor market’s needs. Cook's support for educational enhancements reflects his alignment with efforts to improve career readiness and address workforce demands.

Another significant legislative effort is House Bill 3, focused on funding for border security, which allocates substantial resources towards infrastructure and law enforcement presence to secure Texas's borders. This reflects a priority for public safety and addresses current concerns regarding illegal immigration.

Cook has also indicated a commitment to fostering educational equity through House Bill 1323, which seeks to enhance access to higher education for youth in foster care by simplifying the claims process for tuition exemptions. This legislation demonstrates a compassionate approach to education reform, particularly for vulnerable populations.

As a member of multiple committees that address issues resulting in significant societal impacts—such as juvenile justice, family law, and criminal justice reform—Cook's legislative priorities indicate a comprehensive consideration of both public safety and the welfare of families. He actively engages with community organizations and legislative discussions to ensure that the needs of his constituents are addressed, reflecting a collaborative spirit within the legislative process.

On a personal level, Representative Cook emphasizes community service through his involvement with local non-profits and organizations, such as Mansfield Cares and the Arlington Mansfield Area Salvation Army. He and his wife, Tonya, are active members of their community, alongside their four adult children and five grandchildren. Their commitment to service extends to their faith-based initiatives, illustrating a holistic approach to public engagement and local development.

In defining his political leanings, Cook's sponsorship of education-focused legislation indicates a strong commitment to improving educational opportunities and addressing workforce readiness, while his involvement in public safety measures aligns with more conservative values related to law enforcement and immigration. His legislative record outlines a tenure dedicated to advancing both community welfare and state security, aiming at a blend of social responsibility and conservative fiscal stewardship.
