UPDATE 8:50 p.m. EDT: Law enforcement officers identified the Umpqua Community College shooter as Chris Harper Mercer, age 26, according to CBS News. Officials said he was not a student at the school.

UPDATE 6:30 p.m. EDT: "There's been another mass shooting in America," said President Barack Obama. "That means there is another community stunned with grief." In a news conference from the White House, the president -- clearly shocked, saddened and angry -- responded to a shooting on the campus of Umpqua Community College in Roseburg, Oregon, that reportedly left 10 people dead. 

The president, who said he has visited Roseburg in the past, said the U.S. is the only advanced nation that does not have “sufficient common-sense gun safety laws.” He noted that U.S. states with tough gun laws have fewer shootings, and that other nations have enacted tougher laws after a single incident -- while the U.S. has failed to act after multiple deadly incidents.

“Somehow this has become routine. The reporting is routine. My response here at the podium becomes routine,” he said. “We've become numb to this.”

It was reportedly the 15th time Obama has commented on a mass shooting while president.

Obama named multiple cities where mass shootings had taken place, including Newtown, Connecticut; Tucson, Arizona; and Aurora, Colorado. “It cannot be this easy for someone who wants to inflict harm on other people to get his or her hands on guns,” he said. 

The president said that after each shooting has occurred, critics have accused him of "politicizing" the issue of gun violence.

"This is something we should politicize," the president countered, noting the number of incidents that have taken so many lives in recent years. The president challenged the media to tally the number of Americans killed by terrorism in recent years, and compare that figure to the number of Americans killed by gun violence. He said the gun violence number would be far larger.

Obama compared the effort and financial investment that goes into fighting terrorism and preventable deaths, such as those from auto accidents, and suggested that similar efforts were not being made to prevent gun-violence deaths -- because of politics.

"If you think this is a problem, then you should expect your elected officials to reflect your views," Obama said. He asserted that tougher gun legislation continued to stall in Congress despite the fact that a large majority of ordinary Americans want Congress to take greater action to prevent gun violence.

"Our thoughts and prayers are not enough," he said.

UPDATE 5:03 p.m. EDT: Oregon Gov.

"We are holding the community of Douglas County in our hearts today," Brown said. "The work of the first responders is harrowing."

Brown assumed office in February and has passed legislation to tighten the state's firearm laws. In May, she signed a bill requiring background checks on private gun sales -- the first time in 14 years the state passed laws for stricter gun control.

"We have an obligation to protect Oregonians from gun violence," Brown said. "If we want to keep our kids, schools and communities safe, we must make it harder for dangerous people to get guns."

Further, the Obama administration responded to the tragedy with an urgent call for legislation to control firearms.
