The Trump administration's initial travel ban is set to expire on Sunday. That executive order banned people from six majority-Muslim countries with no "bona fide relationship" to the United States from entering the country. There is increased speculation that President Trump might seek to modify or expand the ban after his tweets following last week's terrorist attack in London, per Bloomberg.
Why it matters: The Supreme Court is set to hear arguments surrounding the ban's current form on Oct. 10, but any modification or expansion of the ban would likely nullify the arguments in that case. It would allow the Court to dismiss or remand the case to a lower federal court, further delaying its consideration of one of Trump's most controversial policies.
