President Donald Trump said Wednesday he'll sign "something" to keep migrant families together at the U.S.-Mexico border. It was unclear exactly what Trump would sign, but his comment came as the homeland security secretary has reportedly drafted an order to keep parents and children together after they are detained crossing the border illegally. Separations have been occurring under the umbrella of a "zero tolerance" approach to illegal border crossings unveiled by Attorney General Jeff Sessions and previously championed by Trump.
