"What happened today in Tulsa is a senseless act of violence and hatred. Sarah and I are praying for the families of those who lost their lives and for those who were injured. I am grateful for the quick and brave actions of the Tulsa Police Department and other first responders who did their best to contain a terrible situation. I have offered Mayor G.T.
