YORKVILLE, Ill. — The small town that boasted of the role it played in Dennis Hastert’s ascent from high school wrestling coach to speaker of the U.S. House spoke bitterly of him on Saturday, a day after prosecutors detailed allegations that Hastert sexually abused several members of the team. The Illinois Republican’s reputation for congeniality contrasts with the government’s portrayal of him in a presentencing filing late Friday as a manipulator who exploited his mentor role to prey on young athletes.
