Barack Obama on Thursday called for “common-sense gun safety laws” after 17 people were killed at Marjory Stoneman Douglas High School in Florida.

"We are grieving with Parkland. But we are not powerless,” Obama wrote on Twitter. "Caring for our kids is our first job. And until we can honestly say that we're doing enough to keep them safe from harm, including long overdue, common-sense gun safety laws that most Americans want, then we have to change."

Obama, who was president during the 2012 Sandy Hook Elementary School massacre that killed 20 students and 6 adults, famously teared up while addressing the nation on gun violence.

At a prayer vigil for those victims, he made a similar remark, asking a Newtown prayer vigil if “we honestly say that we’re doing enough to keep our children, all of them, safe from harm?”
