In Seattle today, a panel of federal judges heard arguments on President Trump's second travel ban.
Following a lawsuit from the state of Hawaii, the ban was blocked in March by a lower court. At issue is whether that ruling should stand.
The federal judges aggressively questioned both sides about the president's authority to restrict visas from six majority-Muslim countries, and if any comments Trump made against Muslims matter.
"How is the court to know if this is a Muslim ban in the guise of a national security justification?" asked 9th Circuit Judge Ronald Gould.
Acting Solicitor General Jeffrey Wall, representing the White House, argued the revised executive order doesn't say anything about religion and should be assessed on face value, not defined by statements made before Trump took office.
Attorneys for Hawaii call the order un-American and an unconstitutional form of discrimination based on nationality.
