A California attorney filed a federal lawsuit Saturday broadly challenging President Trump’s new executive order limiting immigration from Muslim-majority countries in order to combat terrorism, Politico reports.

“The suit, filed Saturday afternoon in U.S. District Court for Northern California, argues that the order intrudes on Congress’ legislative authority and violates the Establishment Clause of the Constitution by discriminating on the basis of religion.”

Washington Post: Trump order causes chaos and outrage

People holding so-called green cards, making them legal permanent U.S. residents, are included in President Trump’s executive action temporarily barring people from seven Muslim-majority countries from entering the United States, Reuters reports.

ProPublica: “It’s also expected to have substantial effects on hundreds of thousands of people from these countries who already live in the U.S. under green cards or on temporary student or employee visas.”

“President Trump’s order to temporarily halt admission to the U.S. from seven Muslim-majority countries is not a Muslim ban, Republicans in Congress, including aides to House Speaker Paul D. Ryan (R-WI),” the Washington Post reports.

“Ryan was among the first lawmakers on Friday to back Trump’s order, which would prevent anyone from Iran, Iraq, Syria, Yemen, Sudan, Somalia and Libya from traveling to the U.S. for 90 days. The order contains an exception for religious minorities, meaning it effectively applies only to Muslims.”

Key sentence: “The majority of Republicans in Congress were silent on the order Saturday.”

“President Trump’s executive order closing the nation’s borders to refugees was put into immediate effect Friday night. Refugees who were in the air on the way to the United States when the order was signed were stopped and detained at airports,” the New York Times reports.

“Mr. Trump’s order, which suspends entry of all refugees to the United States for 120 days, created a legal limbo for individuals on the way to the United States and panic for families who were awaiting their arrival.”

Associated Press: “Cairo airport officials say seven U.S.-bound migrants — six from Iraq and one from Yemen — have been prevented from boarding an EgyptAir flight to New York’s JFK airport.”

“President Trump signed an executive order Friday that would temporarily halt the nation’s refugee program and usher in the most sweeping changes in more than 40 years to how the U.S. welcomes the world’s most vulnerable people,” the Los Angeles Times reports.

“The order would block all refugees from entering the U.S. for 120 days and suspend the acceptance of refugees from war-torn Syria indefinitely.”

Politico: “Trump’s order, which he has described as ‘extreme vetting,’ could pose some legal and procedural headaches for the State Department and the Department of Homeland Security, the two agencies largely responsible for implementing the policies. That’s in large part because some of the language is vague and hard to define.”
