BLOOMSBURG, Pennsylvania — Dave McCormick is standing in front of his parents’ home on the outskirts of this Columbia County college town; it’s been just one day since returning from his “gutting” trip to Israel where he and wife Dina Powell McCormick spent 36 hours visiting an Israeli community at the border with Gaza where scores of Jews were killed last Oct. 7.

He admits he is still shaken from what he and his wife, who served as a deputy national security adviser in the Trump administration, saw, some of which he says is too gruesome for print but should be mandatory for every lawmaker in Washington to experience.
