"Jonah starts crying because he's feeling the pressure in his ears," Bennett told ABC News.
Bennett, was seated alongside Hundley, told FBI agents that she tried to get her son to stop crying when Hundley "told her to shut that ['N word'] baby up."
"I said, 'What did you just say?'" Bennett said. "And he was so drunk that he fell onto my face, and his mouth moved over to my ear and he said it, just directly into my ear."
The 33-year-old mother then says Hundley slapped her son in the face.
"When I had looked at Jonah's face, he had, his eye was swollen…and it was bleeding," Bennett said. "I was just scared to death."
