DOVER, Del. (AP) — Tribune Co. officials believe they can still win a judge's approval to emerge from bankruptcy protection by making changes to its reorganization plan.The judge on Monday rejected Tribune's current plan, as well a rival plan from dissident creditors.Tribune, which owns several newspapers and broadcast stations, including the South Florida Sun Sentinel and the Orlando Sentinel, sought bankruptcy protection in 2008, less than a year after a leveraged buyout led by billionaire Sam Zell left it loaded with debt.Tribune CEO Eddy Hartenstein told employees in an email Tuesday that he believes Tribune can revise its plan in a way the judge will approve.Tribune's chief restructuring officer, Donald Liebentritt, says Tribune will try to submit a revision before a Nov. 22 meeting in bankruptcy court in Delaware.
