No sir. Absolute fact . “itle 8, United States Code §1182(f) gives the president the power “to suspend the entry of all aliens” whenever he finds their entry “would be detrimental to the interests of the United States.” It’s just that simple.
The Supreme Court recently affirmed this power of the President in Trump v. Hawaii. The Court was very clear: “The sole prerequisite set forth in 8 U.S.C. §1182(f) is that the President ‘find[]’ that the entry of the covered aliens ‘would be detrimental to the interests of the United”https://dailycaller.com/2018/10/22/immigrants-invaders-power-president/ States.’”
There are no excuses.
But their entry is already barred by current law. Trump issuing an EO to suspend the entry of already prohibited migrants would make no sense.
Congress can't say to admit them over the President's objection, but they can say how they're to be handled when in custody and what rights they have to apply for asylum.
What more, exactly, could Trump do?
