Lost amid the uproar over the Trump administration’s travel restrictions on citizens from Muslim-majority countries and the impending showdown at the Supreme Court are the insidious ways that the government has already begun to impose a Muslim ban.

It’s doing so through deceptively boring means: increasing administrative hurdles and cementing or even expanding the current travel restrictions that are not under review at the court. The collective impact of these changes will be that a permanent Muslim ban is enshrined into American immigration policy.

Last month, the Supreme Court agreed to hear two cases that challenge the legality of President Trump’s immigration and refugee executive order. And it buoyed the Trump administration’s xenophobia when it put the temporary ban back in place and denied entry to people who lack a “bona fide relationship” with an American citizen or entity. (Astonishingly, the government claims that grandparents, aunts, uncles, cousins and the affianced lack such a relationship, but a federal judge in Hawaii has disagreed.)

While these short-term travel restrictions will be at the heart of what the Supreme Court considers this fall, they have never been the president’s ultimate objective. Instead, his endgame, as he repeatedly made clear on the campaign trail, is the “total and complete shutdown of Muslims entering the United States.” And in a quiet, under-the-radar manner, his administration has been hard at work to make that happen.
