Much of Kent's beliefs from his stated/written position published in 2020 which was the same as President Trump's position of destroying their capability to produce fissionable Uranium for a nuclear bomb AND it's capability with delivery systems has taken a 180.
It is now thought that his new Wife, with her pro-Muslim and antisemitism beliefs has been THE influence on him going off the deep end.
Joe Kent was a frigging crank well before he set foot in the political theatre. The Trump movement never should have embraced people like him or MTG or whatever other crazies the dog drug in. It's not his "new wife" that made his beliefs intolerable, they were always intolerable. Separately, there's massive evidence that he's played footsie with a myriad of white nationalist influencers going back to the time he first showed up in politics (which is why he lost NOT ONE BUT TWO races in a Congressional District Trump won in both 2020 and 2024).
He departed from the Administration (presuming it wasn't because of an actual investigation) because he knows his political career is limited but that there's a lot of money in being an anti-Semitic fringe "right wing" influencer or podcast host or personality or whatever. Just ask Tucker Carlson and Candace Owens. There was a certain person who warned you all about these types of people long ago.
