This comes from a recent interview you can listen to here or read here.
The absolutely most interesting thing from this interview is not the hash smoking detail.
The part that is more important is that Carlson states early on in the interview that he feels that the American president was being blackmailed by Israel into engaging in the Iran war. Carlson basically comes out and implies that the president is compromised and manipulated and knows it, and he had no choice. He doesn’t specifically speculate on how they are controlling Trump. But he says that he’s shocked at the media failure to investigate this. Its really worth listening to this section of the interview. He met Trump 3X and deeply discussed Iran in the weeks before the fighting.
The only thing that comes immediately to mind is that Israel has the Epstein files and are threatening to release them. But it could be something else of course.
He called Trump the anti-Christ and evil.
