NEWBERG, Ore. - A Christian university in Oregon said Tuesday it has punished four students who confessed to hanging a likeness of Democratic presidential candidate Barack Obama from a tree on campus. George Fox University broke the news to students and staff Tuesday afternoon at an all-campus meeting. About 1,000 people attended, said Rob Felton, a university spokesman. A statement from the school said the penalties against the four students were "immediate long-term suspension and public service." The school cited federal privacy rules in not disclosing more about the students or their punishment. The FBI is investigating whether any civil rights were violated. "A criminal investigation is much more rigorous than an academic one, obviously," said Beth Anne Steele, an FBI spokeswoman. She could not say when the investigation would be complete. -Article Continues Off Site
