AUSTIN, Texas (AP) — Attorney General Greg Abbott on Monday defended old rulings by his office that critics say hid problems with the Texas Enterprise Fund and more recent decisions that keep tight wraps on how Texas uses taxpayer money to woo businesses.

The criticism has the Republican, the heavy favorite to win Texas’ gubernatorial race in November, facing fresh scrutiny about transparency and oversight heading into a final debate Tuesday night against Democratic opponent Wendy Davis. An Abbott spokesman called the accusations against his office “political posturing.”
