Dennis Hastert, the Illinois Republican who became the longest-serving GOP Speaker of the House before serving time in federal prison, has died at 84. His death closed a public life defined first by political power and later by revelations of sexual abuse and hush money payments.
Kendall County Coroner Jacquie Purcell confirmed [1] Monday that Hastert died at his home over the weekend. Purcell said the former speaker died of natural causes, and no additional details were released.

Hastert represented Illinois in Congress from 1987 until 2007. He led House Republicans during much of President George W. Bush’s administration and worked with Bush to advance the Republican president’s agenda through Congress.
His route to the speaker’s office opened unexpectedly in 1998 after Newt Gingrich stepped down. Rep. Bob Livingston initially appeared positioned to succeed Gingrich, but Livingston withdrew after revelations involving extramarital affairs.
That political turmoil cleared the way for Hastert, who became known as the “accidental speaker.” He remained in the position longer than any other Republican House Speaker.
Hastert had been an ally of House Republican leader Robert H. Michel and steadily climbed through the Republican ranks. He became chief deputy whip in 1995, criticized the Clinton administration, and later emerged as a central congressional partner for Bush.
His management of the House became associated with the informal Hastert rule. Under that practice, Republican leaders generally brought legislation to the floor only if it had support from a majority of Republican members.
The approach continued influencing legislative battles under Republican speakers who followed him. It became one of the most enduring features of his congressional leadership, even as his wider legacy eventually collapsed under the weight of his criminal case and abuse admissions.
Republicans lost their House majority in the 2006 midterm elections, and Hastert subsequently left leadership. He resigned from Congress in 2007 and entered private work as a lobbyist and consultant.
Federal investigators began examining Hastert’s bank transactions in 2013. Two years later, he was indicted on charges involving structured withdrawals intended to evade reporting requirements and false statements made to the FBI.
Hastert pleaded guilty to the banking offense in 2015. Authorities tied the withdrawals to hush money payments made to a man whom Hastert had sexually abused when the man was a student.
The case exposed conduct from Hastert’s earlier career as a high school wrestling coach. At his 2016 sentencing, Hastert admitted that he had abused boys during those years.
U.S. District Judge Thomas M. Durkin called Hastert a “serial child molester” and sentenced him to 15 months in prison. Durkin also imposed a $250,000 fine and ordered Hastert to participate in a sex offender program.
Hastert was not charged with sexual abuse because the statute of limitations had expired. He ultimately served 13 months in federal prison before being released in 2017.
His imprisonment made him the highest-ranking elected United States official to serve a prison sentence. The conviction and abuse revelations overshadowed the lengthy congressional career that had once placed him among the nation’s most powerful Republican officials.
Hastert was born in Aurora, Illinois, in 1942 and grew up in a farming community. He earned an economics degree from Wheaton College and later continued his education at Northern Illinois University.
Before entering national politics, Hastert spent 16 years teaching and coaching wrestling in Illinois. He was named Illinois Coach of the Year in 1976, later served in the state legislature, and won election to Illinois’ 14th Congressional District in 1986.
Hastert married Jean Kahl in 1973. The couple had two sons.
