The shooting, which killed 12 people and injured many more, upended and paused a presidential campaign fought over small issues. Both Obama and GOP challenger Mitt Romney halted their negative TV advertising in Colorado, and both refrained from criticizing each other in their remarks Friday.
Obama also cancelled a campaign rally planned for Friday afternoon in
Winter Park, Fla. He will instead return to the White House to monitor
the Colorado situation, White House press secretary Jay Carney said.
