President George W. Bush and his wife, Laura, were moved to an armored vehicle on their ranch Friday when a tornado warning was issued in central Texas, the White House said. The vehicle was driven to a tornado shelter on the ranch, and the president, Mrs. Bush and their two dogs sat inside until the weather cleared, deputy White House press secretary Scott Stanzel said. They were never moved into the shelter, he said. The National Weather Service issued a tornado warning after a severe thunderstorm with a history of producing tornadoes was reported 21 kilometers south of Clifton, Texas, and moving northeast. Clifton is 32 kilometers northwest of Crawford.
