'Before the Brexit Referendum' is what's pivotal here.
It was then, that threats against us would've counted ... and, sure enough, Obama issued one.
Since it was literally YEARS, AFTER the Referendum, that Trump told us he'd give us good trade deals once we exited the EU .. you can't credibly claim that there was any way he could, in fact, 'meddle'.
Remember also that, thanks to the disgusting trading straitjacket we're in, thanks to EU rules .. we cannot finalise any trade deals as a standalone national entity, until after Brexit is a fact of life. So, for Trump to say we can have some, after Brexit is completed, does nothing more than acknowledge a status quo which Trump has no say in influencing.
