Senator Ross

 is a friend of Charlie and Daphne Harper's.

The Senator attends the Harpers' weekend house party. He plays table tennis with Samantha who tells him he has a "wicked slam". He playfully retorts that he wishes his wife had Samantha's form.

Later that evening at the cocktail party, he invites Daphne to dance. She declines because of a crushing migraine and he conveys his sympathies.
