(Portland, OR)  --  A man who's accused of groping a 13-year-old girl on a flight from Texas to Oregon is to remain behind bars until his trial.  Authorities say 26-year-old Chad Cameron Camp was arrested earlier this summer after the teen reported he had inappropriately touched her.  A grand jury indicted Camp on a charge of abusive sexual contact.  A trial date has been set for September 6th.
