Trump has never said he would fire Wray. I just posted the video of his interview with Hannity a few weeks ago where he said he appointed Wray because Democrats like him, and only time will tell if he needs to be replaced. Go watch it if you doubt it.
First of all, why would he say that on national TV? You're foolish to think he would, or should. Besides, he doesn't need the attention like DeSantis does. DeSantis is pandering for votes.
A good General doesn't report his war plans ahead of time, and especially not on a news media platform like Fox News, and Scamnity's show. Why would I watch a Scamnity clip even if Trump is in it? I don't watch any news programs on any platform, nor have I watched any of Trump's interviews or his rallies. At 75, I have more important things to do than immerse myself in the cess pool of politics, especially the politics of the main stream media.
