(CNN) - A grand jury in south Texas indicted Vice President Dick Cheney and former Attorney General Alberto Gonzales on separate charges related to alleged prisoner abuse in federal detention centers, Willacy County District Attorney Juan Angel Guerra told CNN Tuesday.
On the southern tip of Texas, Willacy County is on the United States-Mexico border.
Democratic state Sen. Eddie Lucio, Jr. is also charged in the indictment. Michael R. Cowen, an attorney for Lucio, issued a statement calling Guerra a "one man circus."
"In the March 2008 Democratic Primary, 70 percent of the Willacy County voters elected to remove Juan Guerra as Willacy County District Attorney," Cowen said in a statement. "Now, with only a few weeks left in his term, Mr.Guerra has again chosen to misuse his position in an attempt to seek revenge on those who he sees as political enemies."
Cheney spokeswoman Megan Mitchell said, "The vice president has not received an indictment."
The Associated Press reported that the indictment stems from Cheney's investment in the Vanguard Group - an investment management company that reportedly has interests in the prison companies in charge of the detention centers. It also charges Gonzales halted an investigation into abuse at the detention centers while he was attorney general.
