According the NPR people lined up as early as this past Sunday in order to get a coveted seat for the hearing on the President’s travel ban.
 

 
National Public Radio‘s Nina Totenberg has a lengthy, pretty straightforward, story. Here is a bit of it:

The Supreme Court’s Grand Finale: Trump’s Travel Ban

The Trump administration’s travel ban finally reaches the U.S. Supreme Court Wednesday, posing enormous questions involving the structure of the American government and the values of the country.

At issue is the third version of the ban — which the president has complained is a “watered down” version. The court allowed it to go into effect while the case was litigated, but the lower courts have ruled all three versions either violate federal law or are unconstitutional.

Like the earlier two bans, version 3.0 bars almost all travelers from six mainly Muslim countries, and it adds a ban on travelers from North Korea and government officials from Venezuela.

The questions in the case are the stuff of history:

~Can the courts even review a presidential order on immigration that invokes national security?

~Did the president violate the immigration law’s command against discrimination based on nationality?

~And does the executive order violate the Constitution’s ban on religious discrimination?

The travel-ban argument will be the last of the term. And the importance of the argument is not lost on the court. For the first time since the same-sex-marriage arguments in 2015, the court is allowing same-day distribution of the session’s audio. Nonetheless, people started lining up at 7 a.m. Sunday in hopes of snagging a seat Wednesday.

The court itself will be under extreme pressure. There are only about two months left in the term and an unusually large number of cases yet to be decided.

One key question is this one:

Can the court consider Trump’s anti-Muslim rhetoric?

Trump’s Going to Win

Why the Supreme Court will probably uphold the president’s travel ban.

A decision isn’t expected until June.
