President Obama convened the National Security Council in the Situation Room today from 11:30 to 1:00 to review the events in Boston. The President was updated by Assistant to the President for Homeland Security and Counterterrorism Monaco, National Security Advisor Donilon, Attorney General Holder, FBI Director Mueller, and Secretary of Homeland Security Napolitano on the apprehension of Dzhokar Tsarnaev, and the related investigation. He was also briefed by the leadership of the intelligence community, including DNI Clapper and Director Brennan, about our ongoing efforts to combat terrorism and protect the American people. The President commended the work that was done to pursue justice in the Boston Marathon bombing, and underscored the need to continue gathering intelligence to answer the remaining questions about this terrorist attack going forward. As he did last night, the President also expressed appreciation for the efforts made by state and local officials, and law enforcement, in Boston and Massachusetts. Vice-President Biden joined the meeting via video-conference.
