INDIANAPOLIS (AP) -- Lawyers for Indiana Attorney General Curtis Hill have filed court papers challenging the appointment of a special prosecutor to investigate whether he drunkenly groped a lawmaker and three legislative staffers.

The (Northwest Indiana) Times reports documents filed in Marion Superior Court in Indianapolis also challenge the authority of the state's inspector general to build a case against him.

The documents filed on Thursday ask Judge Lisa Borges to recognize there's no immediate need for a special prosecutor because no criminal allegations involving the March incident at an Indianapolis bar have been filed with law enforcement authorities, and they request that she take no further action in selecting one.

Indiana's Republican Gov. Eric Holcomb and the GOP leaders of the Statehouse have called on Hill to resign following the accusations.

The state's top Republican leaders issued statements after an internal legislative investigation memo was leaked earlier this month. The memo says four women accused Hill of inappropriate touching.

Hill has denied the accusations and called the inquiry into his conduct a "prejudicial investigation that is deeply troubling."
