President Donald Trump’s executive order restricting immigration from several Muslim-majority countries is the Muslim ban that he promised on the campaign trail. It violates religious freedom by singling out one religious group—Muslims—for discrimination based solely on how they worship. And that’s not only unconstitutional, it’s downright un-American.

Americans United is filing friend-of-the-court briefs in cases challenging the Muslim ban, explaining why it violates our nation’s fundamental guarantees of religious freedom.

Recent Developments:


  • Feb. 13: The U.S. District Court for the Eastern District of Virginia issued a preliminary injunction that blocks the ban from being implemented in Virginia. The judge's ruling references the conflict between Trump's executive order and the First Amendment's guarantee that government can't single out a religion for disfavor - the basis for AU's argument in the case.
  • Feb. 9: The 9th Circuit Court of Appeals refused the administration’s requests to put the ban back into effect, keeping the hold in place nationwide.

Washington v. Trump

On Friday, February 3, Judge Robart of the Western District of Washington entered a nationwide temporary restraining order, placing the Muslim ban on hold and restoring the status quo. His decision was affirmed by the 9th Circuit Court of Appeals on Thursday, February 9. The Muslim ban remains on hold, nationwide, while litigation continues.

Aziz v. Trump

On Monday, February 13, Judge Brinkema of the Eastern District of Virginia entered a preliminary injunction against the travel-ban portion of President Trump's Executive Order. This injunction, which only applies to Virginia, means that the travel ban will not take effect while the case in Virginia is litigated. Importantly, Judge Brinkema's decision was based on her finding that the ban was indeed a Muslim ban and thus that it likely violated the Establishment Clause.
