Bomb Scare Disrupts Terrorism Drill, Closes MAX Line

"The Topoff dirty-bomb drill turned into a real-life bomb scare this afternoon after a trio of bomb-sniffing dogs alerted authorities to possible explosives on the first floor of the parking garage of the Doubletree Hotel Portland at 1000 NE Multnomah Street. Michael Chertoff, secretary of the U.S. Department of Homeland Security, was scheduled to be at the hotel for part of the Topoff counterterrorism exercise later in the day."
