Democratic presidential hopeful Martin O’Malley said Friday that the massacre in a Charleston, S.C., church should “call all of us to action” on gun violence and mental health services.

“We need to reignite the conversation on a national basis because we suffer from a horrible epidemic of gun violence,” the former Maryland governor said during an appearance on MSNBC’s “Morning Joe,” calling for “common-sense legislation” and “better mental health coordination.”

O’Malley did not offer detailed proposals but cited legislation passed during his tenure as governor that banned 45 types of assault-style rifles and included new permitting requirements for those seeking to buy a handgun, as well as several measures intended to keep guns out of the hands of the mentally ill.
