WASHINGTON — President Barack Obama has reopened a long-running feud with Fox News Channel, branding the conservative U.S. cable network as "ultimately destructive for the long-term growth" of the United States. In an interview published Tuesday by Rolling Stone magazine, Obama took specific aim at Fox's Australian-born chairman and chief executive, accusing Rupert Murdoch of being more concerned about generating profits than promoting an agenda to improve America's well-being. The U.S. president likened Murdoch to William Randolph Hearst, the newspaper baron whose sensational publications produced the term 'yellow' journalism in the late 19th and early 20th centuries.
