Former House Speaker Dennis Hastert has died at 84 at his Illinois home. The longtime Republican congressional leader served as speaker from 1999 to 2007 before a federal banking conviction tied to payments concealing past sexual abuse transformed his legacy.

Dennis Hastert, the former U.S. House speaker who became one of Washington’s most powerful Republicans before his legacy was consumed by revelations of sexual abuse and a federal conviction, has died at age 84.

Kendall County Coroner Jacquie Purcell confirmed on Monday, October 5, 2026, that Hastert died of natural causes at his home in Kendall County, Illinois, over the weekend. He is survived by his wife, Jean, and their two sons.
 

Longest-serving Republican House speaker

Hastert represented Illinois in the U.S. House from 1987 until 2007 and served as speaker from 1999 through 2007, making him the longest-serving Republican speaker in U.S. history.

He became speaker following turmoil within Republican leadership and worked closely with President George W. Bush during much of his tenure. His years leading the House included the aftermath of the September 11 attacks, tax legislation, the Iraq War and expansion of Medicare prescription-drug benefits.

Hastert stepped down from House leadership after Democrats won control of the chamber in the 2006 midterm elections and left Congress in 2007.

Hastert prison case reshaped his legacy

Hastert’s reputation collapsed after federal authorities investigated large cash withdrawals connected to payments intended to conceal past misconduct.

He pleaded guilty in 2015 to illegally structuring bank withdrawals to evade federal reporting requirements. On April 27, 2016, he was sentenced to 15 months in federal prison and fined $250,000.

During the sentencing proceedings, Hastert acknowledged sexually abusing boys decades earlier while working as a teacher and wrestling coach in Illinois. He was not prosecuted for the underlying sexual abuse because the applicable statutes of limitations had expired.

From Illinois teacher to congressional leader

Before entering politics, Hastert spent years teaching and coaching wrestling in Illinois. He later served in the Illinois legislature before winning election to Congress in 1986.

His political rise ultimately placed him among the most powerful officials in the federal government. But the revelations that emerged after he left Washington permanently altered his public legacy.

Hastert’s death closes the life of a former congressional leader remembered both for eight years at the center of Republican power and for the abuse revelations and federal conviction that overshadowed his political career.
