He urged “everybody who’s a person of faith” to pray for the two National Guardsmen shot in Washington, D.C., on Wednesday. He cautioned that much remained unknown, including the motive of the shooter.

“I think it’s a somber reminder that soldiers, whether they’re active duty, reserve or National Guard, our soldiers are the sword and the shield of the United States of America,” Vance said as he delivered a Thanksgiving message to troops.
