and enforce Trump’s bigoted EO, as there was no doubt that Trump’s intent was to ban Muslims from coming into the country based solely on an unwarranted, baseless fear of Muslims, in violation of the Constitution, where an AG is instead obligated to refuse to enforce an executive action which is prima facia un-Constitutional:

“This problem of determining a collective body’s motives simply does not arise, however, when a single individual signs an executive order. So long as Donald Trump occupies the White House, his motivations are the only motives that matter — there’s no need for courts to engage in the admittedly quite difficult task of sorting through dozens of lawmakers’ statements to assess their motives.

Nor is it particularly difficult for judges to determine Trump’s motives in this particular case, since the man literally spent the better part of two years bragging about his desire to ban Muslims on the campaign trail.”

It is obvious to any jurist of good faith that Trump’s EO was clearly intended to ban Muslims from coming to the United States for no other reason than being Muslim.
