A minister, a rabbi and an imam walk into a polling place. No, it's not the beginning of a joke, but a coordinated effort to train clergy to help keep the peace on Election Day. Deema Zein reports.

The effort among Democratic and nonprofit groups includes training volunteers to stand watch outside polling places and report activities they consider concerning.

The diverse, multifaith group is training all the way through the end of October online and in person learning de-escalation techniques and equipping themselves with knowledge of local laws and resources.
