A photograph of blind Chinese dissident Chen Guangcheng with his family is placed on a stand next to ChinaAid Association Inc founder Bob Fu (L) and Human Rights Watch China director Sophie Richardson (2nd L) as they wait to testify in a Congressional-Executive Commission on China hearing on Chen's case, on Capitol Hill in Washington May 3, 2012. U.S. President Barack Obama came under pressure on Thursday to ensure the safety of Chen who briefly took refuge in the American embassy and whose later desperate pleas for asylum from a Beijing hospital bed threaten to fan U.S.-China tensions.
