Refugees Detained at U.S. Airports, Prompting Legal Challenges to Trump's Immigration Order | 28 Jan 2017 | 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 detentions prompted legal challenges as lawyers representing two Iraqi refugees held at Kennedy Airport filed a writ of habeas corpus early Saturday in the Eastern District of New York seeking to have their clients released. At the same time, they filed a motion for class certification, in an effort to represent all refugees and immigrants who they said were being unlawfully detained at ports of entry.
