President Obama on Wednesday visited Colorado — the site of a recent mass shooting and home to new firearms regulations — to rally public support for federal gun control legislation ahead of full Senate votes expected next week and amid Republican opposition.

“I believe there doesn’t have to be a conflict in reconciling these realities,” Obama said in Denver. “There doesn’t have to be a conflict between protecting our citizens and protecting our Second Amendment rights,” he said.

Obama noted that more than 100 days have passed since the shooting rampage that killed 20 first-graders and six adults at an elementary school in Newtown, Conn., and reignited the national debate over access to guns.
