"Judge Theodore Chuang issued the order early Thursday, saying the ACLU and other groups were likely to prevail on their arguments that the ban was unconstitutional because it discriminates on the basis of religion."
"...Hawaii was likely to succeed on a claim that the ban violates First Amendment protections against religious discrimination."
"The groups argued that the underlying rationale of the ban was to discriminate against Muslims, making it unconstitutional. Chuang granted a preliminary injunction nationwide basis."
