Sen. Doug Jones (D-Mountain Brook) Monday called for an end to the Trump administration's "zero tolerance" policy at the U.S. border with Mexico. There have been reports of illegal immigrant parents being separated from children at the border. "This cruel policy needs to end now, but we need workable solutions that can address this specific problem long-term," Jones said. At the White House, Homeland Security Secretary Kirstjen Nielsen said the administration is simply enforcing existing law, and said that "DHS is not separating families legitimately seeking asylum at ports of entry." She also called on Congress to close loopholes and shore-up immigration law. Attorney General Jeff Sessions said critics can end separations by supporting President Trump's plan to build a border wall.
