Clinton’s campaign announced Sunday afternoon the event will be rescheduled, but did not have more detail.

The event was cancelled “because of the tragic attack in Orlando,” a release from Hillary for America said. Early Sunday, at least 50 people were killed and 53 injured when a gunman entered a gay nightclub in Orlando, claiming ties to Daesh or ISIL.

Obama addressed the issue Sunday, calling it a crime of terrorism and hate.

Local Democrats spent several days over the weekend preparing for the visit, according to the USA Today.
