Donald Trump’s executive order, which temporarily banned immigration from certain Muslim-majority countries, and suspended admission of refugees from Syria, sparked immediate and massive protests and action. In addition to the ACLU’s actions, as well lawsuits from the Committee on American-Islamic Relations and the city of San Francisco, three states have now sued the federal government over the executive order, saying that it violates the constitutional rights of people in the United States and establishes a discriminatory law on the basis of religion.
