AUSTIN, Texas (AP) — The Texas prosecutor responsible for investigating public corruption among state officials says he has opened an investigation into the state's troubled $3 billion cancer-fighting agency.

Gregg Cox is director of the Travis County district attorney's public integrity unit. He told The Associated Press on Tuesday that an investigation has begun into the Cancer Prevention and Research Institute of Texas. The agency is also under investigation by the Texas attorney general's office after an $11 million grant to a private company did not receive the proper review.

Cox says his office is starting an investigation not knowing "what, if any, crime occurred."

Cox's unit prosecutes crimes related to the operation of state government.
