LINCOLN, Neb. (AP) — The 31-year-old son of a Nebraska federal judge has been charged with sexual assaulting a woman.

Jonathan Camp, of Lincoln, was arrested Wednesday on a warrant charging him with first-degree sexual assault.

Camp is the son of Chief U.S. District Judge Laurie Smith Camp and Lincoln City Councilman Jon Camp.

An arrest affidavit says the woman told police that Camp drugged her the night of Sept. 8 at a Lincoln home. She said she later awoke to Camp assaulting her.

Camp, who was set to appear in court on the charge Thursday, was being held in the Lancaster County Jail and could not be reached for comment. His attorney, Sean Reagan of Lincoln, did not immediately return a message seeking comment.
