Power line break puts out the lights in Washington, D.C

By Lisa Lambert and Ian Simpson WASHINGTON (Reuters) - A power line broke loose at an electrical substation near Washington on Tuesday, briefly dimming the White House, emptying museums and cutting electricity to government buildings and the U.S. Capitol for hours. The Justice Department and State Department were among thousands of customers whose power was cut in the early afternoon, along with the University of Maryland and some World Bank offices.
