CHICAGO (AP) An indictment against former U.S. House Speaker Dennis Hastert accuses the Illinois Republican of agreeing to pay $3.5 million in hush money to keep someone from the town where he taught high school silent about "prior misconduct." But it offers few hints about a central question: What was the alleged wrongdoing?

The federal grand jury indictment handed down Thursday accuses Hastert of agreeing to pay the money to an unnamed individual to "compensate for and conceal his prior misconduct against" that person.

Legal experts say the fact that prosecutors noted Hastert's tenure in Yorkville, the suburban Chicago town where he taught, in the indictment's first few sentences strongly suggests some connection between the allegations and that time and place.

The 73-year-old Hastert didn't respond to requests for comment.
