Former U.S. House Speaker John Dennis Hastert has died at the age of 84. According to the Kendall County coroner, Hastert passed away at his home over the weekend due to natural causes. In 2016, Hastert admitted in court that he sexually abused boys while coaching at Yorkville High School. A federal judge sentenced Hastert to 15 months in prison and issued a $250,000 fine. The judge referred to him as a "serial child molester."
