Calif. artist sues AP over image of Obama

An artist who created a famous image of Barack Obama before he became president sued The Associated Press on Monday, asking a judge to find that his use of an AP photo in creating the poster did not violate copyright law. The lawsuit filed in U.S. District Court in Manhattan said street artist Shepard Fairey did not violate the copyright of the April 2006 photograph because he dramatically changed the nature of the image.
