Trump's most recent travel ban was not "upheld" by the Supreme Court--it was allowed to take effect while legal challenges are pending.[1] At the same time, the Supreme Court instructed the Courts of Appeals hearing the cases to "render [their] decision[s] with appropriate dispatch," presumably so that the Supreme Court can consider the case and issue a final ruling quickly (well, "quickly" in legal time).[2]

Also, it is inaccurate to claim there is "overwhelming evidence" that the ban is not a Muslim ban, and it is an unhelpful ad hominim attack to call anyone who thinks it's a Muslim ban dishonest. The US District Court in Hawaii held that "EO-3 plainly discriminates based on nationality in the manner that the Ninth Circuit has found antithetical to ... the founding principles of this Nation."[3] I.e., it's a Muslim ban. And the Ninth Circuit recently upheld this opinion.[4]

The Supreme Court might overturn the Ninth Circuit decision, but you might want to edit your comment so it's less wrong.
