MINNEAPOLIS (AP) -- A Minnesota man has been sentenced to nearly three decades in federal prison for producing child pornography.

The U.S. attorney's office says 37-year-old Nicholas Campbell, of Otsego, produced sexually explicit images and videos of two minors. He admitted in court documents that he engaged in a pattern of prohibited sexual conduct with the minors.

Campbell pleaded guilty in April to one count of production of child pornography.

U.S. District Judge Susan Nelson ordered Campbell to serve a 28-year prison term, to be followed by 25 years of supervised release.
