Texas House Speaker Joe Straus released the following statement on the results of Tuesday’s runoffs for seats in the Texas House:

"I want to congratulate the candidates who won their runoffs tonight and will now head to the general election in November. They have worked hard and sacrificed much to earn these victories. Once again, Republican primary voters have shown overwhelming support for responsible candidates who will put their communities first and take a serious approach to the state's challenges. The results in these runoffs and in the March primaries clearly demonstrate that Republican voters want constructive and pragmatic leadership for our fast-growing state."
