The Supreme Court has almost certainly decided what to do about President Donald Trump's travel ban affecting citizens of six mostly Muslim countries.

The country is waiting for the court to make its decision public about the biggest legal controversy in the first five months of Trump's presidency. The issue has been tied up in the courts since Trump's original order in January sparked widespread protests just days after he took office.

The justices met Thursday morning for their last regularly scheduled private conference in June and probably took a vote about whether to let the Trump administration immediately enforce the ban and hear the administration's appeal of lower court rulings blocking the ban.

The court's decision could come any time and is expected no later than late next week, after which the justices will scatter for speeches, teaching gigs and vacations.

Exactly when could depend on whether there are justices who disagree with the outcome and want to say so publicly. It might take time for such an opinion to be written — and perhaps responded to by someone in the majority.

It takes five votes to reinstate the ban, but only four to set the case for argument. Justice Neil Gorsuch, Trump's nominee who was confirmed in April, is taking part in the highest-profile issue yet in his three months on the court.

The case is at the Supreme Court because two federal appellate courts have ruled against the Trump travel policy, which would impose a 90-day pause in travel from citizens of Iran, Libya, Somalia, Sudan, Syria and Yemen.

The 4th U.S. Circuit Court of Appeals in Richmond, Virginia, said the ban was "rooted in religious animus" toward Muslims and pointed to Trump's campaign promise to impose a ban on Muslims entering the country as well as tweets and remarks he has made since becoming president.
