I do not believe Wilson was in the car or even near the call. The widow, or friend of the widow, was “angry” with the conversation (there is nothing Trump could have said because they hated him in the first place) so they made a call to Fredrika, about how Trump was so nasty and made the widow cry. Rather than the clown repeat heresay which is what it was, she claimed she “heard” the call. It’s a lie!
Your theory is sound. I also think that if he used the phrase “he knew what he signed up for...” or some version of that, she was too ignorant to understand the context. Anyone who has spoken to an ignorant person of color has had this experience. One can never underestimate the thin skin of dumb people!
Frederica Wilson was most likely in the car. She is a race hustler who was acquainted with the family. The wife would have gotten a 24 hr notification of Trump’s impending call. Of course the widow would contact her racist friend. Jack Prosobiec, a conservative activist, found Wilson’s pre-Trump-call-tweet, in which she suggested Trump’s biggest screw up to date was coming.
It was a setup.
