MCALLEN, TX - JUNE 23:  A migrant child looks out the window of a bus as protesters try to block a bus carrying migrant children out of a U.S. Customs and Border Protection Detention Center on June 23, 2018 in McAllen, Texas. Dozens of protesters blocked the bus from leaving the center resulting in scuffles with police and Border Patrol agents before the bus retreated back to the center.  Before President Donald Trump signed an executive order Wednesday that halts the practice of separating families who were seeking asylum, over 2,300 immigrant children had been separated from their parents in the  zero-tolerance policy for border crossers.
