Campaign photo diary
Obama honors the victims of The Dark Knight Rises massacre — and more revealing moments on the trail
Both President Obama and GOP challenger Mitt Romney canceled campaign events Friday after a gunman opened fire in a Colorado cinema screening The Dark Knight Rises, killing 12 people and wounding at least 50 others. A "deeply saddened" Romney says he expects "the person responsible will be quickly brought to justice." Meanwhile, President Obama held a moment of silence in Fort Myers, Fla., where he had planned to attend a campaign event. He called on Americans to pray for the victims' families, saying, "There will be other days for politics."
