In May 2015 , Hastert was indicted on federal charges of structuring bank withdrawals to evade bank reporting requirements and making false statements to federal investigators . Federal prosecutors said that the money was to compensate for and conceal deliberately-unspecified misconduct by Hastert against an unnamed individual years earlier . Soon afterward , public accusations emerged that Hastert had sexually abused three male students -LRB- including the aforementioned unnamed individual -RRB- when he was a teacher more than three decades earlier .

Under the agreement , Hastert pleaded guilty to the `` structuring '' charge -LRB- a felony -RRB- , and the charge of making false statements was dropped .

At the sentencing hearing later that month , Hastert admitted that he had sexually abused boys whom he coached . The judge in the case referred to Hastert as a `` serial child molester '' and imposed a sentence of fifteen months in prison , two years ' supervised release , and a $ 250,000 fine .
