'Tucker still has that interview he did months ago with Julian Assange inside Belmarsh Prison in his back pocket.'

this is speculation. if i were british DS there's no way i'd let carlson interview assange - at least not without a lot of censorship. my paranoid brain tells me they prolly told carlson he wasn't to say anything either way - whether he did or did not interview him. all we know is that he entered the prison. and left.
