(Portland, OR)  --  An investigation is underway at Roosevelt High School after a student found a KKK sticker in a boy's bathroom.  KATU reports the sticker showed a person wearing a white sheet with the text "The KKK Wants You."  Roosevelt's principal called the incident appalling and offensive, saying the hateful image has no place in any school.  Officials are looking through surveillance camera footage to see if they can catch the culprit.
