General Dalton McGinnis is a high-ranking officer of the United States Marine Corps. He is first mentioned in Chapter 15. Claire Underwood hesitantly tells her aide in the same episode that she went to college with McGinnis. Frank is due to pin a medal on the general and tells Claire - in a rage - he cannot go through with it because he knows of the incident in which she was raped by McGinnis. She convinces Frank otherwise, as she evidently has other plans in mind.
