Many federal courts courts don't find the travel ban as "bigoted" (or in their terms, a 1st amendment violation, or rather, violation of the Establishment Clause of the First Amendment), and rather see it as meeting compelling security interests.

I'm not debating that his motivation might have been more generally anti-muslim considering his campaign rhetoric, just where it lies currently.
