Denver Mayor Michael Hancock released the following statement:

“Early this morning we learned of another act of senseless violence after a week of threats and unrest across the country. This morning’s attack on the Tree of Life Synagogue has shattered lives and shaken the faith of Americans. Denver mourns with those in Pittsburgh who have lost loved ones and been traumatized by this horrific event. They deserve more than our prayers. They deserve a promise that the basic human principles of tolerance, acceptance and inclusion our country was founded on will be echoed at every level of government and protected fiercely in our communities. This is an important reminder to all of us to be sensitive to our surroundings. If you see something – say something. We are all stronger together.”
