'He's all I have left': Immigrants crossing into the US are unaware and stunned by family separations. Hundreds of immigrant parents are crossing into the U.S. Without proper authorization, unaware that the process to seek asylum now also includes temporary loss of their child. The separation is a result of the Trump administration's new "Zero tolerance" policy, which entails charging nearly everyone crossing the border without authorization with a federal misdemeanor. By doing so, under law, children entering the USA alongside adults fall under the Office of Refugee Resettlement's care while those criminal cases are pursued. Ref. USAToday.
