How many other Texas republicans doubled billed expenses?

I'll bet a lot of them did. Look at the signs.

Take state Rep. Mike "Tuffy" Hamilton. Over the last three sessions, legislative travel vouchers show the Mauriceville Republican charged the state more than $16,000 for mileage — the equivalent of 60 trips between Austin and his East Texas district. He also used his campaign credit card to buy $5,400 in fuel on trips between those two cities. And at least once, he billed both his campaign and the Legislature for the same conference registration.

State Rep. Wayne Christian’s expense reports include similar duplications. In the last few sessions, Christian, R-Center, charged the state more than $16,000 for mileage between Austin and his district, while using $7,000 from his campaign to buy fuel at gas stations between Center and Austin. He reported at least $2,500 in expenses that appear to have been billed both to his campaign and to the Legislature, including airline tickets and conference stays.
