Dennis Hastert case
In 2015, Durkin heard allegations against former Speaker of the HouseDennis Hastert, who was charged with alleged violations of banking laws, reportedly to pay off a victim of sexual abuse. Durkin declared several potential conflicts of interest, including a past donation to Hastert's congressional campaign and past interactions with prosecutors in the case; ultimately, the attorneys did not seek his recusal.[6] Ultimately, Durkin sentenced Hastert to 15 months in prison, far more than the federal recommended sentencing guidelines of zero to six months of prison. The maximum possible sentence was five years. Durkin also described Hastert as a "serial child molester".[7]
