(Portland, OR)  --  Grant High School athletic director Brian Samore is suing the Portland Public Schools district for a half-million dollars.  The lawsuit, which was filed in federal court Friday, alleges Samore was disciplined contrary to the process required by the collective bargaining agreement, following an incident that stemmed from an "inappropriate remark" that he made "in jest" during a conversation with a coach.  Samore was placed on paid leave in January, but now says he no longer works for the district.  KOIN-TV reports PPS officials haven't commented on the lawsuit.
