Inside the ACLU's Fight Against Trump's Muslim Ban, with the Attorney Whose Lawsuit First Halted It

Within 24 hours of President Trump signing his executive order on immigration, the American Civil Liberties Union filed the first legal challenges. The ACLU asked a federal judge to intervene in the case of two Iraqis detained at JFK airport. On Saturday night, U.S. District Judge Ann Donnelly in Brooklyn ordered the men released as part of a nationwide stay on part of Trump's executive order. Her ruling temporarily blocked the deportation of valid visa holders, including those from countries listed in Trump's ban. We speak to Lee Gelernt, the ACLU attorney who helped argue the case.
