President Trump’s ban on refugees and travelers from six Muslim-majority countries will partially take effect this evening, after the Supreme Court said it will examine the constitutionality of the order. The ruling will affect some travelers from Libya, Iran, Somalia, Sudan, Syria and Yemen. Beginning at 8 p.m. Eastern time, foreign nationals from those countries who can’t show a “credible claim of a bona fide relationship” with a person or entity in the United States will be barred from entering the country. The ban is set to last for 90 days, meaning it will expire ahead of an expected ruling from the Supreme Court in October.
