Former USA Gymnastics doctor Larry Nassar, who has admitted to sexually assaulting minors, has been sentenced to 60 years in prison for possessing child pornography."You have to wonder whether he felt he was omnipotent, whether he felt he was getting away with something so cleverly," U.S. District Judge Janet Neff said Thursday in a Grand Rapids, Mich., courtroom, accordingto the Lansing State Journal. "He has demonstrated that he should never again have access to children."Federal prosecutors had sought the 60-year sentence, which is the maximum under sentencing guidelines. "The government said he had 37,000 images of child pornography, including images of children as young as infants," MLive reports.Nassar, 54, still awaits sentencing in two separate state cases that he sexually assaulted women and girls under his care. On Nov. 22, he pleaded guilty to seven counts of first-degree criminal sexual conduct, after maintaining for more than a year that his medical treatments had been legitimate. A week later, Nassar pleaded guilty in another court to three counts of first-degree criminal sexual conduct. In both cases, plea deals dictate a minimum sentence of 25 to 40 years and a maximum of life in prison, the State Journal reports.As NPR's Camila Domonoske reported last month,
