WASHINGTON – The deadly shootings at a movie theater in Colorado have briefly silenced the presidential campaign, prompting both President Barack Obama and Republican challenger Mitt Romney to cut short their schedules and pull advertising in the state out of respect for the victims and their families.

Obama said Saturday in his weekly radio and Internet address that he hopes everyone takes time this weekend "for prayer and reflection — for the victims of this terrible tragedy, for the people who knew them and loved them, for those who are still struggling to recover."

The president said Americans should also think about "all the victims of the less publicized acts of violence that plague our communities on a daily basis. Let us keep all these Americans in our prayers."
