Sen. Wendy Davis is calling for an independent investigation into Attorney General Greg Abbott’s role in the Texas Enterprise Fund. The call comes on the heels of a scathing audit that revealed more more than $170 million was awarded to businesses that never submitted an application.

The Davis campaign is accusing Abbott of using his office to cover up the transition of the funds by hiding documents and denying open records requests that would have proven Abbott knew the applications never existed.

“Greg Abbott has been Attorney General throughout the entire existence of the Enterprise Fund, and he was responsible for acting as its watchdog, monitoring its accounts and recovering misspent money,” Davis said. “For that entire time, Mr. Abbott did not recover one dime of taxpayer dollars for the Enterprise Fund.”

Davis is also demanding that Abbott return the $1.4 million in campaign contributions he received from grant recipients.

According to the Dallas Morning News, the Attorney General’s office maintains Abbott was following state law because releasing confidential applications could put companies at a competitive disadvantage.
