Kappy Trott, the wife of former Rep. David Trott, described the story to Politico on Friday. She said the event occurred amidst a trip to Israel in 2015 with the American Israel Public Affairs Committee alongside nearly 40 members of Congress and some of their spouses.

Once the group landed in Israel, following a laborious travel schedule, she told the publication they immediately jumped onto buses headed for a kibbutz for a demonstration of the country’s Iron Dome defense system.

Exhausted already, she said, many of the spouses of the US legislators on the trip took the bus ride as an opportunity to catch up on sleep.

Mullin, then a member of the House at the time, reportedly had other plans.

Trott said she and her husband personally witnessed the Oklahoma legislator walk “up and down” the bus and stick his finger in the noses of several dozed-off passengers.

“This idiot starts walking up and down the bus with his camera and anyone who fell asleep, he would put his finger in their nose and take a picture,” she said.

…

The story from the eight-year-old trip comes days after Mullin tried to fight the president of the Teamsters labor union during a Senate hearing only to be stopped by 82-year-old Sen. Bernie Sanders.

He’s since gone on a press tour about the incident, telling one podcast he’s not afraid of biting his opponents during a fight.
