The source of the confrontation, as reported by CNN, was a conversation between Doug and Bruce, where Kamala’s husband questioned the rationale behind the Republican’s refusal to shake the former VP’s hand, given his wife’s previous snub.
The former second gentleman directly asked the senator’s husband, “Why would you try to shake my hand when you wouldn’t shake my wife’s hand?”
Neither the former vice president nor the Nebraska senator were directly involved in the interaction between their husbands. Bruce later apologized for the incident.
According to a CNN report, by the time they headed to the car to the Capitol, tempers had cooled, and there was a cordial conversation that touched on golf, among other things.
