"The City of Chicago will fight to ensure that this country remains a welcoming beacon of hope to innocent refugees who seek to escape the life-threatening horrors of war, to asylum seekers and to hardworking, law-abiding immigrants who seek a better life."

Trump signed a revised travel ban last week after a federal appeals court in San Francisco blocked enforcement of his original Jan. 27 order. The new order bars citizens of six Muslim-majority countries from entering the U.S. — down from seven after Iraq was removed from the revised order. Visa and green card holders will be exempt from the ban.

Despite the revisions, the executive order has still faced accusations that it is a discriminatory ban on Muslims and at odds with core U.S. values. Trump has argued that the order is necessary to safeguard U.S. national security and claims that such a measure falls well within his legal bounds as president.
