CHICAGO (AP) — Former U.S. House Speaker Dennis Hastert was for years known primarily for rising from political obscurity in rural Illinois to spending eight years in the nation's third-highest office. Then came a federal indictment in a hush-money case centered on sex abuse allegations.
The 75-year-old pleaded guilty and was sentenced to 15 months in prison. On Tuesday, federal prison records showed he has been released from prison and transferred to a re-entry facility in Chicago.
Here are some key events in Hastert's life and career, and the criminal case against him:
JAN. 2, 1942: Hastert is born in Aurora, Illinois, to a family that runs a farm-supply business.

1986: Hastert is nominated to replace a Republican congressman who is battling cancer. He wins a close election.
1998: Hastert tells incumbent U.S. House Speaker Newt Gingrich that dissatisfaction in GOP ranks makes it unlikely the Georgia lawmaker will hold onto the post. Gingrich resigns the next day.

1999: Hastert is elected U.S. House speaker.
2007: Hastert steps down as speaker after becoming longest-serving Republican in the position.

2010-2012: Hastert allegedly makes 15 withdrawals of $50,000 to pay the person a total of $750,000, paying the money in lump sums of $100,000 cash.
2012-2014: When Hastert learns any withdrawals over $10,000 are flagged, he allegedly begins withdrawing cash in increments just under $10,000.
2013: The FBI and IRS start investigating Hastert on suspicion of violating banking reporting requirements.
DECEMBER 2014: Agents first question Hastert about the huge cash withdrawals. He allegedly says he's taking the cash home because he doesn't trust banks.

JUNE 9, 2015: Hastert pleads not guilty.
