We’re mourning the victims of yet another mass shooting, this time in Kansas City, Kan., where four people were killed and another five wounded.

I continue to be frustrated that these mass shootings and killings occur with regular frequency. Our nation has an obligation to address this ongoing public health crisis. 

For now, we all must pull together to help the community and those affected by this senseless tragedy heal. It’s important to not only remember victims of the shooting, but also their loved ones left behind. Our attention is on them now and in the days and weeks to come.

I also want to thank the emergency responders who quickly and bravely headed to the scene to provide aid and security. We’ll continue working with law enforcement officials to bring those responsible to justice.
