Washington (AP) -- The federal government has agreed to hold five more public hearings on a proposal by an Oregon tribe to build a Las Vegas-style casino in the Columbia River Gorge. Four hearings will be held in Oregon - in Troutdale, Cascade Locks, Warm Springs and Hood River - and one in Stevenson, Wash., officials said. Dates and times have not been set, but officials said they are expected in a few months.
