A worker uses a chainsaw to clear branches from a tree that fell onto the 14th fairway at Congressional Country Club in Bethesda, Md., Saturday, June 30, 2012, after a strong storm blew through overnight. The AT&T National golf tournament was postponed to allow workers to clear the course. More than two million people across the eastern U.S. lost power after violent storms and two people died, including a 90-year-old woman asleep in bed when a tree slammed into her home, a police spokesman said Saturday.
