Josh Duggar wants his December child pornography convictions overturned.This week, attorneys for the former reality TV star filed a motion asking for an acquittal or a new trial. The motion argues that the evidence presented by the prosecution didn't show that Duggar actually viewed the child pornography downloaded onto his computer or that Duggar knew what the visual depictions were of.The motion also argues that the government failed to disclose exculpatory evidence in a timely manner, that Duggar's attorneys weren't allowed to call a witness who also had access to the computer in question, and that a government expert witness should not have been allowed to testify.Duggar was convicted of one count of receipt of child pornography and one count of possession of child pornography. Each charge carries a maximum penalty of 20 years in prison and $250,000 in fine, but only the more serious charge, receipt, will be considered in sentencing.Sentencing will take place in about four months."This is monumental. First and foremost, this shows that no person is above the law, regardless of their status in society, wealth, or fame. No person is above the law," Clay Fowlkes, U.S. Attorney's Office for Western District of Arkansas, told 40/29 News after the conviction last month.Who Is Josh Duggar?Joshua Duggar is the oldest of Jim Bob and Michelle Duggar's 19 children and was a star on the television show "19 Kids and Counting."Joshua served as executive director of the Family Research Council and led rallies against LGBTQ rights, including a seven-state "Faith, Family, Freedom" tour.He resigned from the Family Research Council after sexual misconduct allegations made when he was a juvenile were reported.
