Six-year-old girl heard sobbing in U.S. migrant detention centre reunited with mother

Six-year-old Alison Jimena Valencia Madrid, the separated immigrant child whose tearful pleading with a border agent was heard in an audio that went viral, was reunited on Friday (July 13) with her mother Friday after a separation of just over one month.

The June audio recording said to capture the sounds of immigrant children crying in a detention facility helped rally further opposition to U.S. President Donald Trump‘s “zero tolerance” immigration policy.
