NBC NATIONAL NEWS — The presidential candidates are back on the campaign trail for the first time since the tragic shootings in Colorado.
At a Veterans of Foreign Wars event in Reno, President Obama paid tribute to four veterans killed in Aurora.
"We honor your loved ones. We salute their service. And as you summon the strength to carry on, and keep bright their legacy, we stand with you as one united American family," he said.
Mitt Romney, who discussed the economy with business people in California, couldn't avoid the issue of stricter gun control laws in an interview on CNBC.
"I still believe the Second Amendment is the right course to preserve and defend, and don't believe that new laws would make a difference in this type of tragedy," Romney said.
A moment of silence was held in the Senate to honor the shooting victims and each of their names was read.
Some members of Congress are again calling for stricter gun laws, encouraging parents to push lawmakers for new rules that would stop individuals from buying massive quantities of ammunition and weapons as James Holmes did.
"We have to do something about it. There's no reason in the United States of America, the land of the free, that people have to be afraid to go to the movies," argued Rep. Jan Schakowsky.
Historically presidential candidates have been reluctant to take on gun control as a major campaign issue.
It appears that will hold true in this campaign.
The campaigns kick back into high gear this week.
President Obama will be in Oregon and Washington state on Tuesday.
Mitt Romney, meanwhile, heads overseas to England, Israel and Poland.
