Washington, DC -- The killing of Osama bin Laden has become a campaign weapon for President Barack Obama.
Obama's re-election campaign is portraying his risky decision to go after America's top enemy as a defining difference between him and his Republican presidential opponent.
His team is suggesting Mitt Romney may not have had the guts to order a mission that put lives and perhaps a presidency at stake.
Obama himself is opening up anew, and opening the secretive Situation Room as an interview stage, to hail the one year anniversary of the raid.
Romney's campaign says it is "sad" for Obama to use a unifying event to divide the nation.
