(CNN) - Even former presidential candidates are subject to the occasional annoyances of air travel.
A passenger seated in front of former Massachusetts Gov. Mitt Romney's wife became "physically violent" when the former Republican presidential candidate asked the passenger to move his seat in a more upright position.
The incident occurred Monday when the Romneys were headed from Vancouver, Canada to Los Angeles on an Air Canada flight, according to spokesman Eric Fehrnstrom.
In a statement to CNN, Fehrnstrom said "Romney did not retaliate, but instead allowed the airline crew to respond to the incident."
Following the uproar, the plane returned to the gate where the passenger was removed by airport police. Romney was not injured.
