I have known Trey since 2007, and he served as my campaign and general counsel attorney when I began serving in the state senate. He has a brilliant legal mind, the right philosophy of the proper role and function of government, is a respecter of the 9th and 10th amendments, and is well versed in difficult political and legal battles. President Trump had trust and confidence in Trey, naming him to serve on the Federal Election Commission. Voters in District 21 can have the same trust and confidence in making him your next congressman."

"Trey Trainor has a deep understanding of Pro-Life principles and decades of experience fighting for our Christian values. Texas Right to Life has partnered with Trey in the past to save babies from abortion, protect hospital patients, and uphold the right to free speech. He worked on life-saving court cases, bold political strategies, and creative policy solutions. I look forward to working side-by-side with Trey to do the same in Congress."
