President Obama: All Details Surrounding Bombing 'Speculation' At This Time "When we have more details they will be disclosed. What I've indicated to you is what we know now. We know it was bombs that were set off. We know that, obviously, they did some severe damage. We do not know who did them. We do not know whether this was an act by an organization or an individual or individuals. We don't have a sense of motive yet. So everything else at this point is speculation. But as we receive more information, as the FBI receives more information, as our counterterrorism teams have more information we will make sure to keep you and the American people posted."
