Article: The torch was lit at a park outside at AT&T Park at about 1:17 pm PDT (20:17 UTC), briefly held aloft by American and Chinese Olympic officials. The relay descended into confusion as the first runner in the elaborately planned relay disappeared into a warehouse on a waterfront pier where it stayed for a half-an-hour. There were clashes between thousands of pro-China demonstrators, many of whom said they were bused in by the Chinese Consulate and other pro-China groups, and both pro-Tibet and Darfur protesters. The non-Chinese demonstrators were reported to have been swamped and trailed by angry crowds. Around 2 pm PDT (21:00 UTC), the torch resurfaced about 3 km (1.9 mi) away from the stadium along Van Ness Avenue, a heavily trafficked thoroughfare that was not on official route plans. Television reports showed the flame flanked by motorcycles and uniformed police officers. Two torchbearers carried the flame running slowly behind a truck and surrounded by Olympic security guards. During the torch relay, two torchbearers, Andrew Michael who uses a wheelchair and is the Vice President for Sustainable Development for the Bay Area Council and Director of Partnerships For Change, and an environmental advocate, Majora Carter, managed to display Tibetan flags in protest, resulting in their ejection from the relay. The closing ceremony at Justin Herman Plaza was canceled due to the presence of large numbers of protesters at the site. The torch run ended with a final stretch through San Francisco's Marina district and was then moved by bus to San Francisco International Airport for a makeshift closing ceremony at the terminal, from which the free media was excluded. San Jose Mercury News described the "deceiving" event as "a game of Where's Waldo, played against the landscape of a lovely city." International Olympic Committee President Jacques Rogge said the San Francisco relay had "fortunately" avoided much of the disruptions that marred the legs in London and Paris, but "was, however, not the joyous party that we had wished it to be."

Now answer this question: What wheelchair-bound bearer of the Olympic torch displayed a Tibetan flag?
Andrew Michael
