US President Barack Obama (C) and First Lady Michelle Obama (Top) arrive at Andrews Air Force Base, MD,  November 10, 2009. Obama joins this shaken military community Tuesday in mourning victims of a bloody rampage amid growing questions about the chief suspect's links to militant Islam. In a television interview on the eve of his visit, Obama said the question being asked was: ''Is this an individual who's acting in this way or is it some larger set of actors?''  Major Nidal Hasan emerged from a coma and was able to talk for the first time since he allegedly opened fire on fellow soldiers November 5, killing 13 people and wounding 42 others before being gunned down by a female police officer.
