King posted a tweet with a powerful photo of her father protesting.
"If only Daddy would have known about the power of #Pepsi," she wrote on the photo from the March Against Fear demonstration in 1966.
The commercial features Jenner leaving a photo shoot to join a protest, where she hands a can of Pepsi to an officer, bringing a smile to his face as the crowd turns cheerful.
Though the soda company originally defended the campaign, they have decided to pull the ad.
"Assuming everything that can be said about faux-test Pepsi ad has been said so I'm just gonna go with this: it didn't make me want Pepsi," tweeted Dunham.
