A federal judge has again postponed the child pornography sentencing of a former Navy chaplain and Catholic priest who was convicted of sexually assaulting a Naval Academy midshipman years ago.

Tuesday's scheduled sentencing for 50-year-old John Thomas Matthew Lee of Millsboro has been postponed until February. The latest in a series of sentencing delays came after Lee's attorney complained that prosecutors now want the maximum 50-year sentence, after saying they would ask for about 25 years behind bars.

Lee pleaded guilty in November to producing and distributing child pornography. Authorities say he uploaded child pornography to social networking sites and persuaded several children to send him pornographic images of themselves.

Lee served prison time after a 2007 court-martial on charges including forcible sodomy and failing to tell a sex partner he was HIV-positive.
