AUSTIN — Travis County District Attorney Ronnie Earle is suing to keep secret the details about his investigation of indicted former House majority leader Tom DeLay. 
The Houston Chronicle filed a request under Texas' open records law in March seeking vouchers, hotel and airfare receipts, budget documents, memos and e-mails describing the expenses for the DeLay inquiry and related investigations.DeLay, indicted last year on conspiracy and money laundering charges connected to the financing of 2002 state legislative races, resigned from Congress on June 9. Earle, in his attempt to keep details of his investigation out of public view, appealed to Texas Attorney General Greg Abbott, arguing that releasing the information could compromise the prosecution. The state's lawyer, who reviewed examples of the information, generally ruled that Earle didn't have to disclose secret information related to grand jury investigations. But the attorney general noted that the public records law requires disclosure of "information in an account, voucher, or contract" relating to the expenditure of public monies, the Austin American-Statesman reported Tuesday.
Earle sued last week to overturn the legal opinion. "The first obligation of law enforcement is the protection of the public," Earle said in a statement Monday. "This opinion makes that job harder."
