WASHINGTON — The Nigerian man accused of trying to use a bomb hidden in his underwear to bring down a Detroit-bound airliner on Christmas has been cooperating with investigators since last week and has provided fresh intelligence in multiple terrorism investigations, officials said Tuesday.Umar Farouk Abdulmutallab’s cooperation could prove to be a national security victory and a political vindication for President Obama, who has been under fire from lawmakers who contend the administration botched the case by giving Abdulmutallab the right to remain silent, rather than interrogating him as a military prisoner.In the days following the failed bombing, a pair of FBI agents flew to Nigeria and persuaded Abdulmutallab’s family to help them. When the agents returned to the U.S., Abdulmutallab’s family came, too, according to a senior administration official briefed on the case. The official spoke on condition of anonymity because of the sensitivity of the case.FBI officials continue to question Abdulmutallab, working in collaboration with CIA and other intelligence authorities, the official said. Obama has received regular updates on the interrogation, according to the official.While the interrogation continued, White House and intelligence officials quietly seethed as political rivals accused them of putting lives at risk. That criticism peaked last weekend when Sen. Susan Collins of Maine, in the weekly Republican address, accused the administration of having “a blind spot when it comes to the war on terrorism.”
