Two men seen walking down a Portland street armed with assault rifles told  police they were exercising their Second Amendment rights and hoping to educate  the public on gun rights.

Several calls were made to 911 on Wednesday afternoon, with alarmed residents  reporting two men with guns strapped to their backs walking through the area of  Southeast Seventh Avenue and Spokane Street in Portland's Sellwood  neighborhood.

When police arrived on the scene, they found two 22-year-old men carrying  rifles openly on their backs. The two were also holding valid concealed handgun  licenses in Oregon, according to Fox affiliate KPTV.
