Regarding Trump's intent, the main issue isn't just his words during the campaign, it's also his subsequent words (as,POTUS) about those words. Let's hope the AG is smart & prepared enough to point this out.

JUDGE: “Candidates say many things on the campaign trail... when in truth the poor shlub’s only intention is to get elected.”
AG: Pres. Trump says that he intends to keep ALL those promises, and that they are still his current policy. 
.
JUDGE: “Can we look at his college speeches? How about his speeches to businessmen 20 years ago?”
AG: Yes, we can if he says, "If you want to know what I intend to do now, look at my old college and business speeches. It's all there." This is what any rational person would do. 
.
JUDGE: “What if he said sorry every day for a year? Would that do it for you?”
AG: Trump has NOT said sorry for the Muslim ban he repeatedly promised.  As POTUS, he's done the opposite, refusing to apologize or disavow that promise and insisting he intends to fulfill it.
